High Strain Rate Behaviors of Metals
It is widely recognized that the mechanical behaviors of metals and metal alloys are influenced by at least strain-rate, temperature, and triaxiality. Examples include increases in strength when the strain-rate is increased, and a decrease in strength with an increase of temperature. Factors affecting the mechanical response of structural steels, for example, are important in protective design because dynamic transient loads, like blast, impact or penetration events, can heavily deform metals. The rapid deformation can induce increases in the steel’s temperature through adiabatic plastic deformation.
K&C has tested and modeled numerous metals and metal alloys for various industries interested in the behavior of these materials at high strain-rates. Below are some examples of steel alloys tested at various strain rates and temperatures.
