Computational Solid Mechanics

Lighter weight, stronger and more durable products through modeling and simulation.

 

Our Finite Element Analysis (FEA) services enable your design teams to design with confidence products that will thrive in the real world. Customers trust our FEA analyses to help ensure the integrity of their products and drive business success through innovation.  Our primary services include conducting linear static analyses that reveal stresses or deformations, modal analyses that determine vibration characteristics, and advanced transient nonlinear studies that focus on dynamic effects and complex behaviors.  Whether you are interested in durability, fracture mechanics, buckling, elasticity, or vibrations, we have a wealth of simulation expertise to assist you.


Stress/Strain

Static stress, with linear or nonlinear material models, analysis enables the study of stress, strain, displacement, and shear and axial forces that result from static loading. 

A transient stress analysis is used to analyze events with known time-varying loads, small displacement, and linear material models. With transient stress analysis, we can produce the dynamic response of a structure subjected to time-varying loads.

Critical buckling load analysis (also known as Eigenvalue buckling analysis) examines the geometric stability of models under primarily axial load. Buckling can be catastrophic if it occurs in the normal use of most products.

Modal Analysis

All things vibrate. Vibration can cause gradual weakening of structures and the deterioration of materials (fatigue).  Individual parts have natural frequencies at which they will vibrate without external excitation.  Harmonics occur as individual sections of a part can vibrate independently within the larger vibration. These various shapes are called modes.  Each mode shape has an associated frequency.

The most disastrous consequences occur when a power-driven device produces a frequency at which an attached structure naturally vibrates. This event is called resonance. Modal analysis is most often deployed in order to avoid resonance and destructive feedback.
