Popis: Sheet metal is often used as a raw-material from which structural parts are fabricated through pressing operations. This is the case for example in the vehicle industry where the entire structure of a car is made from sheet material, In many modern cars, crash-protecting parts are made from ultra-high strength steel and such parts are often press-hardened to a tensile strength of 1500 MPa or more in a process with simultaneous forming and quenching. Holes in these parts are sometimes necessary for practical reasons and the fracture criteria used in the design process must be relevant also for such cases.
