Optimizing Additively Manufactured Parts for Adhesive Assembly

Veryst used topology optimization to design an additively manufactured bracket for adhesive assembly and then used cohesive zone modeling to predict the strength of the bonded joint.

Osteotome Fracture

An osteotome unexpectedly failed during a plastic surgery operation. Veryst was hired to explain the failure.

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.

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

FTIR Spectroscopy and Microscopy

Fourier-transform infrared (FTIR) spectroscopy is a method for identifying the chemistry and structure of a material.  FTIR works by measuring the infrared light absorption properties of molecules.  Each functional group in a molecule, such as an alcohol or carboxylic acid, absorbs infr

Medical Devices

Veryst works with clients to develop high-performance, reliable, and manufacturable medical devices. We apply advanced characterization technologies, engineering analysis, and sophisticated simulation software to provide cost-effective solutions to time-critical engineering problems.
