Abstract : The purpose of the Material Response Studies (MARS I) program was to develop new techniques for evaluating the response of current and anticipated reentry vehicle materials to impulsive loads, such as a blast from a nuclear device, and to continue investigations of characterizing the mechanical properties of these materials at high strain rates and elevated temperatures. The four engineering tasks were: Uniaxial Stress Behavior to 10,000/second; Development of Multiaxial High Strain-Rate Test Techniques; Mechanical Properties of Ablative Materials up to Active Ablation Temperature; and Fundamental Study of the High Strain-Rate Behavior of Composites.
