Advanced Finite Element Modeling of Solid Polymers (Part 2)

This class is an extension of the original Part 1 class, and covers in more depth the theory of different material models and includes hands-on exercises designed to teach how to use the different models to solve real problems.

Failure Predictions of Rubbers and Thermoplastics Using FEA

Predicting failure of different polymers can be difficult due to material nonlinearities and sensitivity to the load environment. In this class we will discuss different techniques that can be used to predict both brittle and ductile failure, including fatigue, of different types of polymers.

Finite Element Modeling of Solid Polymers (Part 1)

This two-day, web-based course covers a review of polymer mechanics theory, techniques and tools for experimentally characterizing polymers, and hands-on training on how to perform accurate finite element simulations of polymer components. This is the original training class that we have been gi

High Strain Rate Testing and Modeling of Solid Polymers
Foams, elastomers, and other polymers are often exposed to high strain rates and impact events. Due to the materials' strain-rate dependence, it is important to have accurate experimental data in order to select and calibrate a suitable material model. This class will demonstrate the use of Split Hopkinson bar tests and traditional uniaxial tests, and provide hands-on exercises for how to use the experimental data to calibrate suitable material models.

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.

Case study

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.
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.
PEEK Temperature Dependence
PEEK 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 Parts
Veryst 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.
