Advanced Testing and Modeling of Polymers for FE SimulationThis 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.
Testing and Modeling of Polymers for FE SimulationThis course is intended for finite element (FE) engineers that simulate polymers and are interested in advancing their modeling skills beyond hyperelastic material models. The class covers the foundations of continuum mechanics for material modeling, including hyperelasticity, metal plasticity, linear viscoelasticity, and advanced viscoplastic material models. The class also covers test methods and discuss how to design test plans for material modeling.
MCalibration®: Inverse Calibration
This half-hour, web-based class offers an overview of using inverse calibrations in MCalibration. This course will review how to set up MCalibration to run an inverse calibration, extract the data, and run the calibration.
Bottle Impact Failure and Material ModelingImpact 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) CalibrationCohesive 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 TestingComposite 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 HosesA 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 DamperElastomer 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 SimulationAccurate 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.
PEEK Temperature DependencePEEK materials are increasingly used in a variety of industries with elevated temperature applications. This example shows how Veryst Engineering developed a temperature-dependent, nonlinear model of PEEK behavior for use in commercial FEA codes.
Strength of Additively Manufactured PartsVeryst can predict the ultimate strength and failure modes of design concepts generated using topology optimization and produced using additive manufacturing. We use advanced finite element analysis (FEA) that accounts for the nonlinear behavior of the material being used to make the part.

Structural Finite Element AnalysisVeryst offers leading expertise in advanced finite element modeling, particularly for complex, nonlinear problems. We can address problems that other finite element analysis consultants either cannot or are not sufficiently experienced to do well.
Veryst’s mechanical testing capabilities have been developed over the past decade and are motivated by the need for high quality data to characterize complex polymer behavior. We tailor our test programs based on our deep understanding of polymer and material mechanics and the challenges complex
