3. Fatigue Analysis & Fracture Analysis

Through Fatigue analysis and Fracture failure analysis, we are able to provide you with definitive answers to your most pressing fatigue life prediction investigation studies through expert numerical analytical simulation of fatigue life prediction.

Durability and Fatigue – Failure Analysis

Component failures are in many cases not due to a single event, but due to accumulative damage caused by a series of events.
The typical fatigue process is to maintain stress/strain levels below the acceptable for the required number of cycles. Multiple loads often occur and will have a different cycle requirement.
ANSYS Fatigue or the more advanced nCODE can accurately predict the component life.
An alternative approach is to understand that a crack occurs in the component. The fracture is analyzed to determine whether it will further propagate, and if so, at what rate.

5. Explicit Dynamics Simulation

Explicit dynamics solutions are well suited to analyzing physics that involve severe load forces applied over a short span of time (in the order of micro- or milliseconds).
It can also be used for solving highly non-linear physics challenges, including occurrence of wear contact, exceedingly large strain, and material structural failure.

Dynamic Analyses

The dynamic analysis allows the user to account for the time-dependent characteristics of their structure.
For linear dynamics, the initial effort is often to determine the natural frequencies through a modal analysis. Results are then utilized in a harmonic, shock, seismic, random vibration or transient simulation to determine deflections, stresses, and strains. For nonlinear dynamics analysis, a direct transient simulation can be performed.

Some of the related FEA software feature includes:

● Rotordynamics for power generation, transportation, electronics and process equipment.
● Vibration isolation to minimize energy transmission to structures
● Stress stiffening/spin softening to investigate impact of dynamic characteristics
● Single and multi-point response spectrum
● VibroAcoustic analysis to determine sound response to excitation
● High-performance computing

6. Kinematic Analysis

A kinematic analysis is often considered when the motion or displacement of an assembly prototype is dominated by the joints within the functional system.
A kinematic analysis is deemed to be rigid when deflections are totally characterized by the joints or have flexibility when the stiffness of the moving components is taken into consideration.

Some of the related FEA software capabilities include:

● Load cycle prediction for fatigue investigation input
● Critical point trace plot
● System level simulation analysis to determine interaction with parameter controls
● System stability
● High-performance computing
7. Optimization

7. Optimization

These days as the globalized business landscape has become more competitive, even an incremental increase in material performance can be instrumental in the success or failure of the product.
Optimization can be quantified in many different methods, such as cost, pressure drop, weight, deflection and useful life.
Through the use of either parameterization or topological optimization, engineering designs can be significantly improved to maximize their performance potential.Additional parameters that are of a close relation with Optimization are Sensitivity and Robustness.
There are cases where an engineering design performs perfectly under an ideal manufacturing and environmental conditions, but slight variations can quickly degrade this.
Often the best design isn’t the one that has the best performance for one singular operating condition but has good performance over a variety of environmental conditions.
Having a design performance that is not sensitive to external variables allows the opening up of machine tolerance. This helps to reduce cost by eliminating the need for tight tolerances.

Featured FEA Case Studies   

Elasto-Plastic, Soil-Structure Interaction Analysis of Foot-Rest

 

Environment: Abaqus 6.12, Hyper Mesh 13.0.
Objective: To do a literature review and find out the suitable method to simulate a soil-structure interaction. Need for soil-structure interaction: Footrest is a part of 46m Military load class 70 modular bridge. there are four-foot rest over which the bridge is mounted. The load to the bridge gets transferred to the ground through the footrest. an initial fear analysis was carried out considering the ground to be rigid. when summer trials were held in loose soils, the footrest was found to be failing and cracks started developing.
Method & Software used: modeling was done in Abaqus 6.12 and the hyper mesh was used to mesh the model. An elastic-plastic analysis was carried out. The soil was modeled as a single solid continuum.
contacts were defined between soil and structure. It was assumed that relative motion between the soil and structure is impossible Two cases were considered. where the soil was considered to be elastic in case one and the soil was considered to undergo plastic deformation in case two. The soil was made considerably big such that soils boundary condition doesn’t affect the model.
Conclusion: Footrest was found to be failing exactly in the same location as in original component. Further design optimization was performed manually and the FEA analysis was carried out. The footrest was found to be safe.

Dynamic Analysis of Human-induced Vibrations in Mountain Foot Bridges

 

Objective: To evaluate the level of comfort the bridge offers, while a pedestrian walks on the bridge.
Method & Software used: Abaqus 6.12 was used for the complete simulation. Beam and shell elements were used for the simulation. mountain footbridge is a single span 32m bridge, pedestrian comfort is inversely proportional to the length of the bridge.
Vibration pattern that arises when a human walks on the bridge is well documented and is mathematically expressed as a function of Bridges’s natural frequency. The natural frequency closest to the human-induced vibration is used to simulate resonance condition. A modal analysis was carried out to find the natural frequencies, followed by a transient analysis was carried and acceleration of the bridges at the center of the bridge was documented.
Conclusion: The accelerations were well below the limits specified in the documents, which implies very fewer vibrations while walking and high comfort.
