Finite Element Analysis (FEA)

Advanced finite element modeling is done in our company for various issues.
Although companies and industrial plants usually have design offices, our company has a higher level of expertise, experience, and knowledge for finite element modeling (FEM).
The company uses ABAQUS, ADINA, COMSOL, ANSYS, ANSYS, and LS-DYNA finite element software as required.
In this company, people with different specialties evaluate the problem from different aspects and then design and model it. At all stages, one always monitors the problem for continuous evaluation to prevent human error, which is the most common error in software calculations. Our capabilities in this area include the following:

fast response

The model is quickly transferred from CAD software to CAE software and the process of network production and application of boundary and loading conditions is applied.

Materials with nonlinear behavior

A variety of situations that affect the behavior of the material can be modeled in the software. Strain rate dependence, temperature dependence, damage, anisotropy, and other factors are considered according to the need for the problem. Sometimes models of materials are not available in finite element software; In this case, the necessary coding is done to add the desired model. Ability to model elastomeric materials, foam, thermoplastic (soft heat), thermostat (hard heat), wood, composites (fabric, texture, multilayer, needle, etc.). Calibration of materials for entering experimental results into finite element software is also done by our experts.

Contact

Simulation of various issues related to the call is done in this company. Frictional behavior of materials and structures, adhesive joints, surface tension, wear as well as multi-physical problems in which contact is involved such as temperature, acoustics, electromagnetism or fluid flow are modeled in finite element software.

Validation

The simulation requires validation. “All simulations are wrong unless proven otherwise,” says the great masters. For this purpose, experimental tests are used to confirm the accuracy of the simulations. In these tests, special and sensitive conditions of the problem that can affect the correctness of the results are considered.

An advanced model of materials in finite element simulation

In many finite element simulations used for metal and polymer parts, the most important step is to identify and select the appropriate mechanical model for the material so that it can simulate all of its mechanical properties observed during testing (e.g. Viscoelastic and nonlinear viscoplastic response). In our technical engineering company, various models have been coded for metal, polymer, ceramic, foam, and even concrete and soil construction materials and can be used as valid auxiliary software in Abaqus software.
