A New method for Evaluating wrinkle Resistance of sheet metals |
| |
Abstract: | A new method for evaluating the wrinkle resistance of sheet metals was studied with a nonuniform biaxial tensile test of square sheet metals. The index of the wrinkle resistance in the new method is the ratio of biaxial loads under a certain level of strain. It has several advantages: the measurement is simple,the repeatability is good, and the simulation of sheet metal forming can well represent the real wrinkle resistance of sheet metals. |
