Solid Modeling & Finite Element Analysis (FEA)

With the growing need of custom testing services, there is the need for designing custom test rigs, fixtures, samples, and parts.

Solid Modeling

Solid modeling is a set of mathematical principles and computer modeling of three-dimensional solids. This process is different from related modeling, such as geometric modeling, because of its emphasis on physical dependability.

Using solid modeling, Innovative Test Solutions designs, models, and builds a wide range of components to fulfill the testing requirements outline by the client.

Finite Element Analysis

Finite Element Analysis (FEA) of critical design components in the early design stage can greatly enhance the overall product quality.

FEA can create a substantial advantage in testing the performance of a product. It can also reduce product cost significantly, especially if applied early in the design cycle.

Analysis results identify the critical areas that carry the bulk of stresses caused by deformation or vibration. Analysis also determines less important areas in which a material reduction may be possible.

Innovative Test Solutions has the ability to perform the following finite element analysis: 

Capture the effects of large displacements on your design: Examine the impact of large displacement and changes to the 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.
