Testing

Case study

Tensile Testing of Nitinol Wires
Shape memory alloys, like nickel titanium alloy (nitinol), are common in medical device applications. Nitinol is often used in fine wire form and can be difficult to test. Veryst has developed methods to test fine nitinol wires in uniaxial tension at different temperatures to obtain a stress-strain curve.
Testing of Climbing Shoe Rubbers
The material properties of a climbing shoe’s outsole rubber directly affect a rock climber’s performance. Veryst performed friction and compression testing of two climbing shoe rubbers to quantify and compare their performance.
Testing Polymers in Cryogenic Temperatures
Many engineering applications require understanding the behavior of polymers under cryogenic temperature conditions. Veryst developed a test fixture and method to test materials submerged in liquid nitrogen (LN2) at its boiling temperature of -196°C.

Service

Abaqus Material Models
Veryst has designed test plans to calibrate material models to many advanced models in Abaqus, including the Bergstrom-Boyce (Hysteresis) model, Low Density Foam model, and Parallel Rheological Framework (PRF) models.
Adhesive Joints & Interfaces
Veryst assists clients with the selection of adhesive materials, development of bonding processes, and mechanical analysis of interfaces.
