The article considers a calculation method allowing us to take into account the non-zero
initial stress-strain state of the multi-layer cylindrical structure elements due to static
internal pressure. These calculations made it possible to estimate the influence of the
initial stress-strain state on the material structure transition to the plastic stage under the
effect of short-term dynamic loading.
Keywords:
stress-strain state, internal pressure, dynamic load, yield strength, elastic-
plastic materials, shock-wave processes.
