Case Studies

During sloshing, liquid exerts a dynamic force on the surrounding vessel, which may cause leakage or damage to the vessel or its supporting structure. We used a mesh-free smoothed particle hydrodynamics (SPH) method to predict liquid sloshing and its effect on the deformation and stresses in a vessel.

Tempered and plate glass are manufactured to produce very different fracture patterns when they break. Veryst can use this information to identify installed glass products and discuss the implications of their use.

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.

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.

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.

Electroosmotic (EO) pumps are driven purely by electric fields and have no moving parts. Cascading EO pumps reduces voltage requirements. Veryst used computational fluid dynamics (CFD) and semi-analytical equivalent circuit theory to analyze the complex behavior of these pumps.

Thermal management is crucially important for battery performance in consumer products, electric vehicles, and grid-level storage systems. In this case study, Veryst used multiphysics simulations to evaluate different thermal management strategies in prismatic and cylindrical battery packs.

Tires experience large, complex deformation during use, and the highly filled rubbers are difficult to model. Veryst designed and calibrated a custom material model to capture the mechanical behavior of the tire to improve the design.

New total joint replacement prostheses often use ultra-high molecular weight polyethylene (UHMWPE) in load bearing components. Design engineers need to understand the stress and strain distributions in order to extend device life.
