Failure Analysis
Case study
Plastic Clip Failure
A plastic clip used to retain a patient support failed, resulting in an occupant death. Veryst was asked to determine the cause of failure.Small-Scale Friction Measurement
Medical devices, combination products, consumer products, and manufacturing processes often include components that slide past each other. These products and processes can fail when the friction forces between the surfaces are too high, due to surface roughness, lubrication, materials, or environmental conditions. Here Veryst introduces a specialized fixture to measure the friction between a small metal wire and three polymer materials, to select a backup supplier for dual sourcing that would maintain low friction in a medical device.Strength of Additively Manufactured Parts
Veryst can predict the ultimate strength and failure modes of design concepts generated using topology optimization and produced using additive manufacturing. We use advanced finite element analysis (FEA) that accounts for the nonlinear behavior of the material being used to make the part.Service
Additive Manufacturing
Veryst Engineering helps clients realize high-performance additively manufactured parts. Our strong foundational knowledge in materials science and mechanics coupled with practical expertise in experimental methods and engineering software make us uniquely qualified to solve complex additive manufacturing challenges.Adhesive Joints & Interfaces
Veryst assists clients with the selection of adhesive materials, development of bonding processes, and mechanical analysis of interfaces. We employ chemical characterization, mechanical testing, and advanced computational methods to design robust adhesively bonded structures and to understand delamination failures.Failure Analysis
The consultants at Veryst provide failure and root cause analyses using core engineering disciplines to evaluate different failure scenarios. Engineering specialties we apply to failure analyses include: mechanical engineering, materials science (metallurgy, ceramics, polymer science, compo
