Other Areas of Expertise

In addition to computational simulation, Veryst Engineering provides engineering services in the areas of design, manufacturing processes, and failure analysis. Veryst Engineering’s consultants have specific expertise in the following areas:

Polymer Analysis

Development, analysis, and modeling of polymer properties and component performance. Our expertise in this area includes experimental characterization and failure analysis of polymers. We develop advanced polymer material models than account for viscoelasticity, viscoplasticity, anisotropy, damage, and temperature dependence.

Material Testing

Advanced testing of mechanical properties including the effect of temperature and strain rate. Our testing covers a broad range of material types including elastomers, thermoplastics, foams, fluoropolymers, biomaterials, bioplastics, hydrogels and fabrics. We have in-house testing facilities for uni-axial tension and compression, 3 or 4 point bending, volumetric compression, shear, fatigue and long term creep. Most of the tests can be performed at temperatures ranging from 80°C (-112°F) to 280°C (536°F). We also have a split-Hopkinson bar test system for very high strain rate testing.

Failure and Root Cause Analysis

Determination of causes for component and system failures. We use our expertise in material sciences (metallurgy, ceramics, polymer science and composites) and manufacturing technologies to evaluate different failure scenarios. The tools we use include scanning electron microscopy (SEM), atomic force microscopy (AFM), mass spectroscopy, infrared spectroscopy, and x-ray diffraction (XRD).

Featured COMSOL Projects

Peristaltic pump fluid-structure interaction

Peristaltic pumps move fluid by squeezing an elastomeric tube causing the fluid inside the tube to follow the motion of the roller. Veryst Engineering developed a fluid-structure interaction model of the operation of a peristaltic pump. The model captures the deformation of the tube, rollers and the fluid, and is useful for investigating the effect of pump design variables such as tube occlusion, tube diameter and roller speed on the flow rate and the stress state in the tube.

Sea floor energy harvesting

Veryst Engineering developed proof-of-concept models for a device for harvesting energy from constant low speed ocean floor currents in order to power ocean sensors. In the design shown here a bluff body is inserted in the flow path to generate Karman vortices which are then directed to an energy conversion device.

Thermal analysis of a Calrod

A Calrod is a heating element that converts electricity into heat via Joule heating. Veryst Engineering developed a multiphysics model of a Calrod composed of a heating wire, surrounded by a magnesium oxide insulation, and encased in an stainless steel tube. Heat transfer from a Calrod occurs via conduction and radiation.

Bergstrom-Boyce material model for elastomers

The Bergstrom-Boyce material model is accurate for modeling the behavior of a wide range of elastomers/rubbers. The model accounts for nonlinear rate dependent deformation of elastomers, and also accounts for Mullins damage. We implemented the equations governing the viscoelastic deformation and Mullins damage using the "Distributed ODEs and DAEs" COMSOL capability.
