Measuring the plastic strain ratio of sheet metals: A useful tool for evaluating materialDetermining how much a metal can deform before thinning or fracture occurs is necessary for designing a reproducible forming operation. Testing the incoming sheet material is also essential because material properties may vary from coil to coil and affect the part quality and scrap rate. Understanding a material's plastic strain ratio and how to measure it are crucial in accurately establishing a material's formability.

Stamping 101: Material guidelines: Properties and characteristics that affect formabilityEach metals has its own blend of physical, chemical, and surface properties and characteristics. Knowing about the major work metals (not tool steels), their properties, grades, and characteristics helps to achieve the best results in stamping and forming best results.
