The effect of strain rate of steel material
Abstract
This project presents the effect of strain rate of steel material. Two different experiments
are required in order to investigate the effect of strain rate of steel material. The first
experiment is using Universal Testing Machine to investigate the effect of strain rate at
static condition while the second experiment is using Split Hopkinson bar technique to
investigate the effect of strain rate at dynamic condition. The behavior of material at high
strain rates is important for application such as structural impact, automotive safety
engineering, and metalworking. In automotive industries, steel has been used as material in
some of component. Due to dynamic condition of strain rate occurrence during vehicle
crash it is important to analyze the strength of component.
