Impact Simulation & Testing

Impact events are transient and often require explicit finite element (FE) simulations. Veryst has extensive knowledge in impact modeling and specializes in the optimization of explicit finite element models for impact simulations with advanced FEA codes including Abaqus, ANSYS Explicit, and LS-DYNA.

Materials experience very high strain rates (100/s to >1,000 1/s) during impact events. Accurate material characterization at similar high strain rates is essential to model material behavior accurately. Veryst has developed a set of comprehensive, state-of-the-art, experimental capabilities, including drop towers and custom test machines. Veryst also offers material model calibration and validation with high strain rate testing.

Veryst offers custom impact testing on polymer products and systems to validate FE simulations.

Veryst provides advanced options for failure prediction with material failure models with native and custom material models. Veryst also has extensive experience in modeling the failure of connections and mechanisms, such as bolts, joints, and snap fittings.

Explicit simulation produces datasets that are both large and noisy. Veryst specializes in techniques such as data truncating and filtering that extract desired information without distortion or aliasing, as well as advanced programming and scripting that make data processing an automatic part of the simulation.
