Evaluating Car Body and Exterior Sheet Steel Strength
Strength evaluations of sheet steel used for car doors and hoods are performed as standard tests. In an effort to strike a balance between fuel economy and safety, sheet steel manufacturers compete aggressively to develop lightweight, high-strength materials.
To develop this type of sheet steel and perform quality control and machinability inspections, testing machines are used for tensile testing to obtain process-hardening coefficients (n values), rupture strength and elastic modulus.
The Shimadzu Autograph features a variety of grips, displacement measuring devices and width sensors designed for these tensile tests, and with the TRAPEZIUMX computer system, they can be performed efficiently by anyone.
