Golf ball impact simulation with comparison to experiment.

Veryst Engineering has extensive experience in impact simulation and testing.  We provide clients with accurate and comprehensive solutions for impact applications with particular strengths in the following areas:

Explicit Transient Simulation: Impact events are transient and typically require explicit 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 and LS-DYNA.

High Strain-Rate Material Characterization: Materials during impact experience very high strain rates (> 1000 sec-1). Accurate material characterization under such high rates is pivotal for accurate simulations. Veryst offers a comprehensive analysis suite that includes material testing with state-of-the-art techniques including Split Hopkinson Pressure Bar (SHPB), material model calibration, and validation studies.

Modeling of Failure Mechanisms: Veryst provides advanced options for failure prediction with material failure models from its PolyUMod Library--models that are otherwise not available through commercial FEA codes. Veryst also has extensive experience in modeling the failure of connections and mechanisms, such as bolts, joints and snap fittings.

Data Processing and Analysis: 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.

Veryst’s impact simulation practice has served clients from many industries, including consumer electronics, sports equipment, consumer appliances, and petrochemical engineering.  For further information, email
