DYNAMIC COMPRESSION TESTING OF A STRAIN-RATE MATERIAL,
Abstract
Complete compressive stress, strain and strain-rate data have been obtained at room temperature for annealed Lexan, a typical polycarbonate material, for strain-rates of 0.0016 to 4000 in./in./sec. It has been observed that although this material is violently sensitive to the rate of loading at lower strain-rates, this sensitivity becomes negligible as the rate of strain is increased. The existence of a limiting curve will permit a rate independent analysis to be used to predict material response at extremely high rates of strain. (Author)
