Mechanical Modeling & Simulation

Exponent uses modeling and simulation to assist in design and failure analysis by evaluating the effects of loads on systems or products.  The team comprises an interdisciplinary staff with experience in applying its integrated capabilities to a breadth of engineering issues.  Our projects range from medical devices to satellites to downhole tools for the oil and gas industry.  Exponent utilizes the most advanced software available for finite element analysis (Simulia Abaqus, ANSYS, and LS-Dyna) and fracture mechanics (FRANC3D and NASCRAC), and maintains a high performance computing cluster for executing simulations.  The team can tackle any modeling problem, no matter the size of the assembly or the complexity of the materials involved.  Additionally, Exponent’s laboratory facilities enable our team to obtain experimental results to supplement and validate our analytical models.
