What fatigue damage model do you suggest to use in numerical simulations?

I want to simulate fatigue damage of foams (like PVCs). What fatigue damage model do you suggest? What model is regularly used in Industry? is there any one who simulate fatigue damage in Abaqus? Any information is welcomed...  Thanks in advance

Stochastic continuum model for mycelium-based bio-foam

Mycelium, the root structure of fungi, grows naturally as a biodegradable filamentous material. This unique material has highly heterogeneous microstructure with pronounced spatial variability in density and exhibits strongly non-linear mechanical behavior. In this work we explore the material response in compression, under cyclic deformation, and develop an experimentally-validated multiscale model for its mechanical behavior. The deformation localizes in stochastically distributed sub-domains which eventually percolate to form macroscopic bands of high density material.

Mechanics of Mushroom as a material

We recently characterized a unique material developed from root structure (Mycelium) of mushroom. Mycelium has a filamentous network structure with mechanics largely controlled by filament elasticity and branching, and network density. We report the morphological and mechanical characterization of mycelium. The monotonic mechanical behavior of the mycelium is non-linear both in tension and compression.
