Where does FEA (Finite Element Analysis) fit in the Engineering Development Process?

Today, FEA Simulation fits in both the Mechanical design engineer’s and FEA Consulting Engineers analyst’s Development process. Early in the Product design Stage FEA (Finite Element Analysis) plays an Integral role in Encouraging Technological innovation through the Capability to digitally experiment with New design.
In order to do this, the FEA CFD Analysis functionality must be presented in a Forward-looking environment that is very familiar to the Product design engineer; that is the 3D CAD Platform Environment, which is possible with an embedded FEA Finite Element Analysis solution.
Best Performing Marine Structure Consultants are twice as likely to automate Complex assembly Boundary contact definition and 4-times as Probable to automate 3D geometry clean-up.
Further analysis Recognized how Best Performing FEA Pipe Stress Engineering organizations address these Confrontations. Top Performing FEA Pipe Stress Analysis Consulting Companies are those who are much more successful than their Adversaries. 
Compared to other Structural Engineer Consultant competitors, they are more Adept, more innovative, produce higher quality products, and do a much better job meeting cost targets. 
In addition to ease of use, other Important aspects Assist to Assimilate Finite Element Simulation Capabilities Much closer to 3D CAD Modeling, including model associativity, which allows the Mechanical design’s Inherent analytical Performance Metrics such as 3D CAD geometry topology, material Physical properties, load Forces and Constraining boundary conditions inherent in the CAD model, to also carry over to the finite element analysis simulation Modeling. Therefore, any changes Done to the Pre- Existing 3D CAD model will carry through and Refresh the Ansys FEA Analysis Modeling automatically.
Also, with embedded FEA Fatigue Simulation post-processing analysis, the 3D CAD system’s geometry manipulation tools can be used to make any necessary model refinements quickly and easily – in the case of Solid Edge, synchronous technology can be leveraged.

Featured FEM Modeling Case Studies

FEM Modeling

FEA Modeling of a Stiffened Composite Panel

Objective: The objective of the FEM modeling was to model a Stiffened Composite panel and load it in Compression up to Collapse. Determination of Failure location and Failure Modes. This involves the usage of a suitable failure theory in the FEM software (IL: FEM Software).
The FEM simulation approach used was FEM modeling the various parts such as Skin, Stiffeners, UTM Casings and assembling them with the enforcement of Constraints (Tie, MPC) and Shell to Solid Coupling.
Compression load was applied from a Reference point via Multi Point Constraints defined between the Reference point and the nodes on which load will act. Using FEA software, the precise physical load is applied through displacement controlled mode on the RP and this is thereby applied on the nodes of the panel. Hashin’s intralaminar failure theory in combination with fracture energy based stiffness degradation approach was used as the failure theory.
Through the successful modeling of the Stiffened Composite panel in the FEA analysis, our FEA consultant was able to simulate till collapse and determined the failure locations, failure modes, and magnitude of collapse load.
