POREQST extension to shock-release hysteresis of graphite
Abstract eng: Because of its thermal and shock-wave attenuation properties, porous graphite is widely used in the aerospace industry. No residual compaction of this material after compression-release cycles has been experimentally observed that contradicts the usual numerical dynamic porous models such as POREQST. We suggest to enhance the latter taking into account this phenomenon. The new model HPOREQST was tested for simulating plate impact experiments at moderate pressure onto porous graphite. It proved to be in far better agreement with experimental data than the original model.
