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).

Medical Device Development
Engineering assistance in the development of medical devices. The
services we offer include failure analysis, CAD modeling, virtual
prototyping, intellectual property assessment, and design for
manufacturing and assembly, We have helped firms developing vascular
stents, biopsy devices, minimally invasive cardiovascular devices, hip
implants, catheters, guidewires, and surgical instruments. We provide
assistance in the development of PMA, 510k, and CE Mark submissions.

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.
