Materials Properties - Information from Non-Destructive and Destructive Experiments Via Simulation.

Abstract

This work addresses procedures to obtain robust information on the mechanical properties of materials via simulation of relevant nondestructive and destructive experiments. Under this grant the general problem of information on properties of the fiber-matrix interface in composite materials is examined. A novel procedure for obtaining quantitative information on mechanical, including failure, properties of the interface is utilized, i.e., by simulating actual experiments in detail, including fiber properties of the interface is utilized, i.e., by simulating actual experiments in detail, including fiber breakage, matrix, yield and/or cracking, and interface failure. In a recent relevant study, the procedure was implemented for simulating commonly performed experiments, i.e., the fragmentation test for metal matrix composites (MMCs), the pushout and pullout tests for MMCs as well as ceramic matrix composites (CMOs). Herein the so-called transverse test is examined in detail with emphasis given on residual stresses. One major finding is that the (transverse) properties of the interface depend strongly on the residual stresses present, which, in turn, depend on the geometry of the structure/specimen examined and on the processing temperature.
