Solid Modeling and FEA

Solid Modeling

With the growing need of custom testing, there is the need for designing custom test rigs, fixtures, samples and parts. Innovative Test Solutions, Inc. designs, models, and builds a wide range of various components to assist with a customers need.

Finite Element Analysis

Finite element analysis (FEA) can give you a huge advantage in testing a products performance. FEA of critical design components in the early design stage can greatly enhance the overall product quality. FEA can also reduce product cost significantly, especially if applied early in the design cycle. Analysis results identify critical areas which carry the bulk of stresses caused by deformation or vibration, as well as less important areas in which a material reduction may be possible.  It is a great tool to use for comparing analytical results with actual test results.

Innovative Test Solutions, Inc. has the ability to perform the following analysis:

Capture the effects of large displacements on your design:

Examine the impact of large displacement and changes to loads and restraints.
Transition easily between linear and nonlinear simulations.
Study nonlinear buckling and snap-through events.

Simulate products made with nonlinear materials:

Optimize designs with hyperelastic materials. (ex: rubbers and silicones)
Conduct an elasto-plastic analysis to study the onset of yield as well plastic deformation.
Examine creep effects and material changes with temperature.

Perform dynamic analysis of parts and assemblies:

Simulate time history loading, steady-state harmonic input, and random vibration excitations.
Use uniform and multi-base motion systems to model structures with non-uniform support excitations.
Input excitation curves of forces in random vibration analysis.
Study stress, displacement, velocity and acceleration with time, as well as RMS and PSD values for stress, displacement, velocity, and acceleration.

Simulate composite materials:

Study multilayer shell bodies to examine how each layer has its own isotopic or orthotropic material properties, thickness, and orientation.
