Increased environmental concerns are driving the auto industry to continual

weight reduction of vehicles.

Need for quick, advanced analysis, simulation, and visualization techniques

for automobile components before they are manufactured in production line

Complexity in handling the changes to computation

Increased deformation rates change the mechanical behavior of a material.

It is important to study the high strain rate properties of the materials to

achieve optimum design, further weight reduction , safer vehicles and

increased mileage
