Battery Pack Impact SimulationFrom 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.
Bottle Impact Failure and Material ModelingImpact 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 TestBiodegradable 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.
Cohesive Zone Model (CZM) CalibrationCohesive zone modeling is a powerful tool for predicting delamination in adhesively bonded structures. Veryst engineers use their expertise in experimental and computational fracture mechanics to calibrate cohesive zone models for accurate prediction of adhesive failure.
Golf Ball Impact SimulationAccurate simulation of golf ball behavior during impact with a club is challenging due to the nonlinear impact event, the complexity of the polymeric ball material at the high strain rates experienced during impact, and the scarcity of material properties at these high strain rates. Veryst Engineering developed an accurate model that accounts for these complexities.
High Strain Rate Testing of Fiber-Reinforced ThermoplasticsUnderstanding composite materials’ impact response as a function of fiber direction is important for a wide range of uses, from automotive applications for crashworthiness to consumer product uses for drop and impact resistance. Veryst evaluated the high strain rate response of both glass fiber and carbon fiber reinforced PEEK (polyether ether ketone) using the Split Hopkinson Pressure Bar test method.
High Strain Rate Testing of PolymersThis case study demonstrates the testing and calibration of a polycarbonate material at a high strain rate of 1000 sec-1. The testing was done with the Split Hopkinson Pressure Bar (SHPB) system and the calibration is performed with the MCalibration® software, originally developed by Veryst Engineering.
Impact Fracture Toughness of Adhesive JointsVeryst developed a new test method for measuring fracture toughness under impact loading that does not require measurement of load or crack length. We have used this method to help clients in the automotive and electronics industry understand how adhesives fail under impact conditions.
Polymer Material Models in Different FE PackagesAll commercial FE packages provide material models for polymers, but Veryst Engineering’s PolyUMod® material library has advanced material models at the leading edge of polymer mechanics. We demonstrate the accuracy of a PolyUMod material model with native material models from Abaqus, ANSYS, and LS-DYNA.
