FEMFAT laminate: Fatigue strength analysis of continuous fiber reinforced resin

It is possible to analyze the fatigue strength of each layer of continuous fiber reinforced resin under multi-axial loading.

FEMFAT laminate is a module for fatigue analysis of continuous fiber reinforced resins (available in ChannelMAX). Within the MAX module, fatigue strength evaluation can be conducted individually for each laminate. The front and back sides of each laminate in the composite material are subject to damage calculation. The analysis method is adapted to the laminate material using the stress types of "Critical Component in Critical Plane," evaluating fiber breakage and interlayer breakage within the fibers. Furthermore, when using a solid element model (typically 8-node hexahedral elements), delamination can also be assessed. For damage calculation, static strength characteristics (tensile strength and compressive strength) and fatigue strength characteristics (S-N curves) are required for loads in the parallel and perpendicular directions to the fibers, as well as for shear loads in the laminate plane. It supports shell and solid elements defined with COMPOSITE properties using Abaqus inp files and odb files. *For more details, please download the PDF or contact us.*
