High Strain Rate Testing

Three important points collectively highlight the need for high-speed testing:


Bend Testing

Tensile testing cannot be used to determine bendability, since these are different failure modes. Failure in bending


Testing & Characterization

Many demands are placed on automotive body structures which influence the material selection process. The impact on


Tensile Testing



Friction and Friction Testing

Friction is a restraining force that limits metal flow resulting from contact with another surface during sheet


Bulge and Dome Testing

Local necking during uniaxial tensile testing limits the characterization of the stress-strain response to true


RSW Joint Performance and Testing

Acceptable weld integrity criteria vary greatly among manufacturers and world regions. Each AHSS user needs to
