Non-local energy based fatigue life calculation method under multiaxial variable amplitude loadings [PDF]

open access: yes, 2013
Reliable design of industrial components against high cycle multiaxial fatigue requires a model capable of predicting both stress gradient and load type effects. Indeed, taking into account gradient effects is of prior importance for the applicability of

Hydrostatic compression on polypropylene foam [PDF]

open access: yes, 2014
Models currently used to simulate the impact behaviour of polymeric foam at high strain rates use data from mechanical tests. Uniaxial compression is the most common mechanical test used, but the results from this test alone are insufficient to ...
