Title:
FEA-based Development of a New Tool for Systematic Experimental Validation of Nonlinear Strain Paths and Design of Test Specimens 
Abstract:
To achieve high accuracy in finite element simulation, it is beneficial to model forming limit curves (FLCs) for nonlinear strain paths, since FLCs based on linear strain paths inaccurately predict the failure of parts that undergo nonlinear strain paths. Standardized Nakajima or Marciniak tests are used to create a FLC for linear strain paths. For common strain paths, the shapes of the specimens are well-known. Only a limited set of nonlinear strain paths can be generated by using these tests....    »
