Summary
Polymers are becoming increasingly important in structural design, enabling the fabrication of components such as dampers, lattice structures, and key elements in aerospace prototyping. However, their structural behavior, in particular fatigue behavior, is not yet fully understood. In particular, temperature-dependent and nonlinear responses can significantly complicate the constitutive modelling of these materials.
This Special Issue aims to address current gaps in the fatigue modelling of polymeric materials. It promotes the development of comprehensive simulations of mechanical behavior, including accurate constitutive descriptions—also accounting for nonlinear effects—and reliable fatigue damage indicators. Moreover, the application of advanced fatigue approaches, such as the theory of critical distances, the average strain energy density method, and phase-field modelling, traditionally developed for metals, is encouraged to evaluate their applicability to polymers.
The topics of this Special Issue include, but are not limited to:
· Comprehensive fatigue tests on polymeric specimens;
· Application of the theory of critical distances to polymer fatigue modelling;
· Application of the average strain energy density method to polymers;
· Application of phase-field modelling to polymer fatigue;
· Computational analyses of Fatigue behavior of polymeric lattice structures;
· Development of constitutive models, including temperature-dependent and nonlinear behavior, to be used in fatigue modelling of polymers.
