Curve a has the highest strain rate ( behavior like brittle) followed by curves, b, c and d in decreasing order.
What is Strain rate ?
The rate of deformation brought on by strain in a material over a given period of time is known as the strain rate. This measures the rate at which material distances change over a certain length of time.
What is tensile test?
Tensile testing is a destructive test method that reveals details about the metallic material's tensile strength, yield strength, and ductility. It assesses the amount of stretch or elongation that a composite or plastic specimen must undergo to reach its breaking point.
The rate of deformation called the strain rate. The strain rate is higher if the deformation takes place quickly. While ductile materials experience less strain, brittle materials experience more. The stress-strain graphic shows that the strain rate rises vertically. Curve a exhibits the highest strain rate (brittle behavior), followed in decreasing order by curves b, c, and d.
