Finite Element Analysis (FEA) Consultants

FEA consultants make up a big core of our team of FEA consulting engineers and CAE consultants here at our Singapore simulation office in BroadTech Engineering. Time to market Introduction is also Highly critical for competitiveness. Getting to market first enables FEA Structural Engineering Consultancy companies to capture market share before competitors can respond.
 
At the very same time, Engineering product cycles performed in typical Structural SImulation Services performed have gotten Very short, the window of opportunity for maximum Business Profit potential has Significantly Lowered After releasing a product, FEA Structural Engineering Services companies have less time to recoup their development investment and collect revenue before the Core Commercial product is Surpassed by the next Updated version or worse, replaced by a competitor product. With this in mind, Engineering Structural Simulation Services companies need to be as Operational as possible. Investments in design FEM Simulation Software tools can help improve efficiencies, as well as help teams, catch problems earlier and avoid release delays

Structure Conceptualization and Optimization of Battery Heater Bracket in an Electrical Car

1. FEA Simulation objective:

To deliver the structure concept (3D model) to customers based on the required weight reduction without compromising structure stiffness (1st Eigen Frequency) when the material is replaced from Aluminum to Plastic

2. FEA Simulation Methodology and Approach:

Hypermesh, Optistruct, and Catia are employed. Based on the original metal design, a preliminary 3D model is prepared to conduct Topology Optimization Analysis. FE model including the bracket and the assembled parts are built-in Hypermesh (3D tetra elements, material properties, BCs, and Lanczos frequency analysis), subsequently, a Topology Optimization model is set up (design and non-design area, objective, constraint, etc.). The calculation is conducted by an Optistruct solver. After analysis, the values of eigen frequency and topologies are listed with different possible fractions of total volume. The final 3D model is drawn by Catia, but the design is reasonably modified compared with the given topologies considering the feasibility of a real manufacturing process.

3. Outcome & Conclusion: 

Wall thickness and rib pattern are key factors of the design to achieve the stiffness and weight reduction requirements.
 
 

Fracture FEA analysis on a Nuclear control rod standpipe (CRSP)

1. FEA Simulation objective:

This project aimed to conduct a fracture analysis on a control rod standpipe (CRSP) which is a nuclear component on behalf of a customer (EDF Nuclear Energy, UK)
The fracture assessment aimed to demonstrate the structural integrity of the CRSP under specified reactor trip conditions for a postulated defect contained in one of the welds within the CRSP. The fracture assessment was conducted following R6 a nuclear fracture assessment standard. The fracture assessment was carried out by demonstrating that the J-integrals for a postulated defect under the specified reactor trip conditions were below the critical J-integrals for the postulated defect to propagate.

3. Outcome & Conclusion

Results from this project showed that a defect of a certain size would not propagate under the specified reactor trip conditions. Note that the defect size chosen was the maximum defect size not detectable during inspections. Also, this project evaluated the critical defect size for a circumferential semi-elliptical defect configuration.

Glass Fiber Reinforced Polymer Footbridge

1. FEA Simulation Objective:

The objective of this study was to propose a concept of a footbridge that can be prefabricated, transported, and installed as a single piece on site. The bridge had a single span with a length of 28m. The cross-section was designed as a box with a 3m wide upper flange and tapered at the bottom flange. As a result of the first analysis, intermediate webs were added to better distribute stresses, and cross-section high was varied across the span. 
The whole project can be divided into two stages: in the first stage multiple layers of short, randomly oriented glass fibers embedded in polymer resin GFRP, the cheapest material option, were proposed. This did not require composite mechanics.
  1. Material study – Micro damages of single fiber can appear much earlier than ultimate strength. Thus, von Misses stresses were limited to 40% ultimate tensile strength.
  2. Constructability – it was an academic project however bridge could be constructed after further study and detailed design
  3. FEA – LUSAS, British FEM software dedicated to civil engineering problems, was employed. Half a year earlier Our FEA Consultant started my study about FEM, mainly with books written by O.C Zienkiewicz. LUSAS had an extensive element library, good manuals rich in theoretical justifications, and a clean interface, it created a good environment for my study. Our FEA Consultant r FEA Consultant studied the performance of different possible elements, refined mesh, investigated the behavior of displacements’ derivatives.    
  4. Stress analysis – Stress trajectories were studied. The initial thickness of plates had to be increased to prevent micro damages.
  5. Shell buckling – vertical plates (web) were subjected to out-of-plane buckling. First, web stiffeners were considered, thus increasing the Complexity of the bridge. The height of the plates was reduced to reduce buckling effects.
  6. Geometry modification – thickness of plates was increased in the middle part of the span. The height of the section was varied along the span.
  7. Verification of modified model – stresses were limited to the value chosen in the first point, stability of shells was ensured.
  8. Dynamic performance – natural frequencies were compared against possible pedestrian-induced vibrations. No risk of pedestrian-induced vibrations was identified.   
 
It was also presented during on nationwide conference for engineers and was rewarded with a 2nd award for best work.
In the second stage, the bridge was studied further, this time in terms of composite mechanics. Here glass fiber reinforced mats were stacked together with carbon fiber reinforced mats. Different combinations of glass and carbon layers together with the orientation of carbon fibers were examined.
  1. Composite mechanics study – principals were studied, it was beside the scope of my first-degree study. Tsai-Hill and Tsai-Wu criteria of composite material strength were later used in the analysis.
  2. Implementation in LUSAS – Simple examples was studied to verify them with engineering intuition.
  3. Geometry – Resultant geometry from the first stage was applied.
  4. Study of different configurations and orientations of layers – in the result locally increased thickness was not required to meet stress limit requirements. The Upper and bottom flange was reinforced with two layers of carbon FRP. Mass was reduced by approx. 20%

Computational performance and numerical Precision

Finite element analysis (FEA) Simulation Modeling has Steadily Expanded in size as FEA engineering consultants continue to Solve Complicated Technical problems. Today, complex FEA models with literally millions of degrees of freedom (DOF) have become the New Standard FEA Consulting Engineers Face Daily.
At the same time, computers have also evolved and multicore processors have become the de-facto standard.
 

Recursive domain normal modes

Recursive domain normal modes (RDMODES) is a high-performance eigen solution technique that significantly reduces the cost of eigenvalue Numerical Simulation for Relatively Big FEA models.
In combination with RDMODES, Simcenter Femap NX Nastran offers several options for calculating Quick frequency responses during the FEA Stress Analysis and is Capable Of Solving Big FEA Element structural and vibro-acoustic Numerical Modeling typically used in Automotive NVH.
Similar to Ansys Finite Element Analysis, Simcenter Femap NX Nastran also Strongly supports CDH/AMLS software to drastically accelerate Simcenter Femap NX Nastran modal and frequency response Numerical simulations.
RDMODES supports both SMP and DMP for greater Numerical solution ability.
Scalability for this Type of Numerical method has been achieved with a Count Upwards of 512 central processing units (CPUs).
The Highly recursive DMP solution can Enable Finite Element Consulting Engineers to Effectively Computing Huge Engineering problems more than 100 times faster than the Lanczos method on a single processor Core.
