Abstract: Determining the constitutive response of polymer matrix composite materials is a critical requirement for using such materials in naval applications. This information is essential to structural design, material qualification and certification, material manufacturing, maintainability, and structural health monitoring. Over the past decade, we have been engaged in an effort to automate both the massive multiaxial testing of composite coupons required for constitutive characterization and the computational methodologies required for extracting the constitutive response from these tests. Here we report on the completion of the first recursively defined, custommade, hexapod testing machine, capable of 6-degree-offreedom (6-DoF) tests, and the first high-throughput, data-driven campaign of experiments for the purpose of constitutive characterization. Our approach is motivated by the data-driven requirements of employing design optimization principles for determining the constitutive behavior of composite materials.
