On the temperature dependence of the cyclic compression behaviour of a thermoplastic vulcanizate elastomer

open access: yesPolymer Testing, 2022
Effects of temperature on the uniaxial cyclic compression of a polypropylene based thermoplastic vulcanizate were studied in the range −40 °C–100 °C. The effect of temperature on the stress level was similar to that on the storage modulus from dynamic ...

Evaluation of combinatorial algorithms for optimizing highly nonlinear structural problems

open access: yesMaterials & Design, 2023
Optimizing highly nonlinear structural problems can be very challenging due to the large number of parameters. Classical compliance minimization does not work for such problems. Common optimization algorithms also do not find good solutions.
