Testing and Modeling of Polymers: High Rate and Traditional Testing

Design engineers often use polymers in impact protection applications, and these designs experience high strain rates during impact.  Polymers are viscoplastic by nature, so the material response is highly dependent on the strain rate.  Collecting data on your polymer (elastomer, thermoplastic, f

Case study

Accelerated Creep Testing of Polymers with Time-Temperature Superposition
A medical device designer wanted to forecast the creep performance of a plastic part for at least two years. Veryst tested the material using time-temperature superposition to characterize the material’s long-term performance quickly and efficiently to determine if the design performs adequately after two years.
Battery Pack Impact Simulation
From smartphones and cameras to wireless headphones and battery packs, portable electronics proliferate. Consumers expect excellent resilience to device drops, increasing pressure on manufacturers to test thoroughly and optimize their designs. Veryst utilized its unique expertise in accurately modeling complex materials, conducting high strain rate testing, and simulating impact events to simulate the drop impact of an external battery pack.
Bioabsorbable Coronary Stent Design
Bioabsorbable materials, such as polylactic acid (PLA), are finding increasing applications in medical devices. These polymers exhibit a nonlinear anisotropic viscoplastic response when deformed, which requires a sophisticated material model for accurate finite element predictions.
Bottle Impact Failure and Material Modeling
Impact modeling of polymers is important given their use in consumer products as both structures and impact protection. Accurate FE models of impact events require high rate testing, advanced modeling, and a thorough understanding of polymer failure.
Cell Phone Drop Test
Biodegradable polymers are becoming increasingly attractive for consumer product applications such as electronic devices and disposable packaging. Modeling these materials during impact is challenging due to the complexity of the physical event and the scarcity of appropriate material models for biodegradable polymers.
Composite Testing
Composite materials, such as carbon fiber reinforced polymers, provide a high strength-to-weight ratio for structures ranging from aerospace components to biomedical implants to consumer sports products. These materials require thorough and specialized methods for material testing and validation due to their anisotropic material properties.
Creep Testing of Polymers at Elevated Temperatures
Polymers are prone to deform slowly over long periods of time when subjected to applied load, a phenomenon known as creep. Over time, the deformation can grow so large that the part no longer functions as intended. Veryst utilized creep testing to compare material choices and set temperature specifications for polymers.
Design of Reinforced Hoses
A high-strength reinforced hose failed in service under normal operating conditions well before its intended design life. Inspections of the subject hose revealed that failure was mainly due to delamination.
