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.

Advanced Structural Mechanics Using COMSOL Multiphysics

This class will cover most of the structural analysis capabilities in COMSOL Multiphysics including large deformations, material models, contact mechanics, and convergence issues.  The class includes technical lectures and hands-on COMSOL examples.

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.

Multiphysics Analysis for Medical Devices Using COMSOL Multiphysics

This two-day course will cover the efficient use of COMSOL Multiphysics to solve problems in the medical device industry.  It covers modeling challenges specific to medical devices, and several examples including tissue ablation and a cardiovascular application.  The class includes technical lect

Case study

Bioabsorbable Coronary Stent Design
Bioabsorbable materials, such as polylactic acid (PLA), are finding increasing applications in medical devices. These polymers exhibit a nonlinear anisotropic viscoplastic response when deformed, which requires a sophisticated material model for accurate finite element predictions.
Broken Rail Train Derailment
A train derails with an ensuing fire and evacuation of a neighborhood. What was the root cause of the derailment?
Calrod Thermal Analysis
How fast does a Calrod heat up and how high are the stresses during heating? To answer these questions Veryst Engineering developed a coupled electric-thermal-structural multiphysics model of the Calrod, accounting for conduction, convection, and radiation.
Cell Phone Drop Test
Biodegradable polymers are becoming increasingly attractive for consumer product applications such as electronic devices and disposable packaging. Modeling these materials during impact is challenging due to the complexity of the physical event and the scarcity of appropriate material models for biodegradable polymers.
CFD Modeling for Ventilation System of a Hospital Room
Efficient ventilation can contribute to reducing the energy consumption of buildings and minimize the risk of airborne infection in hospital rooms. Veryst used computational fluid dynamics (CFD) to simulate ventilation in a hospital room as well as the dispersion of particles and droplets.
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.
Delamination in Microfluidic Valves
A commonly encountered failure mode in microfluidic devices is delamination between adjacent device layers. Veryst examined the influence of control channel geometry on the delamination pressure of a pneumatic microfluidic valve using finite element analysis.
