Abstract

We present a multiscale design system (MDS) for fatigue life prediction of composite materials and structures based on the combination of reduced order spatial homogenization, adaptive cycle block integration, and inverse calibration of fine scale material parameters against available experimental data. Fatigue of composites is modeled as a multiscale problem in space and time where reduced order mathematical homogenization is used for spatial upscaling (or coarsegraining), and the cycle block scheme, which estimates the rate of degradation of material properties in a single cycle and then adaptively projects it over n-cycles, is used to for temporal upscaling. The MDS, which includes a flexible user interface for incorporating experimental data, has been seamlessly integrated in ABAQUS and a graphical user interface (GUI) has been developed.
