Testing and Modeling of Polymers: High Rate and Traditional Testing

Design engineers often use polymers in impact protection applications, and these designs experience high strain rates during impact.  Polymers are viscoplastic by nature, so the material response is highly dependent on the strain rate.  Collecting data on your polymer (elastomer, thermo

Advanced Testing and Modeling of Polymers for FE Simulation

This course is intended for finite element (FE) engineers that simulate polymers and are interested in advancing their modeling skills to the most advanced material models available for polymers.  We will review the foundations of continuum mechanics for material modeling and dive into advanced material model calibrations, including inverse calibrations, failure modeling, and anisotropic material modeling.

Adhesive Testing and Material Model Calibration for FEA of Bonded Joints--2023

In this free, one-hour webinar, we will share the basics of how to develop material models for adhesives to be used in commercial finite element analysis (FEA) codes.  We will cover both continuum material modeling and cohesive zone modeling. 

Bottle Impact Failure and Material Modeling

Impact modeling of polymers is important given their use in consumer products as both structures and impact protection. Accurate FE models of impact events require high rate testing, advanced modeling, and a thorough understanding of polymer failure.

Cohesive Zone Model (CZM) Calibration

Cohesive zone modeling is a powerful tool for predicting delamination in adhesively bonded structures. Veryst engineers use their expertise in experimental and computational fracture mechanics to calibrate cohesive zone models for accurate prediction of adhesive failure.

Composite Testing

Composite materials, such as carbon fiber reinforced polymers, provide a high strength-to-weight ratio for structures ranging from aerospace components to biomedical implants to consumer sports products. These materials require thorough and specialized methods for material testing and validation due to their anisotropic material properties.

Design of Reinforced Hoses

A high-strength reinforced hose failed in service under normal operating conditions well before its intended design life. Inspections of the subject hose revealed that failure was mainly due to delamination.

Elastomer Foam Vibration Damper

Elastomer foams make excellent vibration dampers, but accurately designing these dampers requires an advanced material model. Veryst calibrated a PolyUMod® material model to design the vibration damper.

Golf Ball Impact Simulation

Accurate simulation of golf ball behavior during impact with a club is challenging due to the nonlinear impact event, the complexity of the polymeric ball material at the high strain rates experienced during impact, and the scarcity of material properties at these high strain rates. Veryst Engineering developed an accurate model that accounts for these complexities.
