Abstract

A brief description of the progress on mechatronic multi-degree of freedom material testers developed at the US Naval Research Laboratory (US-NRL) is given to describe the enabling technology for acquiring data that encapsulate both the recoverable and the dissipative behaviors of various composite material systems under quasi-static multiaxial loading conditions. The notion of material equivalence is then explored from the perspective of the data-driven dissipative behavior of multiaxially tested composite laminates. Emphasis is given by considering the same ber within the same resins and vice versa. The eect of dierent curing conditions is also examined. As a follow-up, an overview of a multiscale computational framework is also outlined for the purpose of introducing multiscale implications of how macro- scale behavior in terms of experimental data can yield information about the behavior of materials at lower length scales.
