Abstract: Characterizing dynamic characteristics of structures with uncertainty is an important task that provides critical predictive information for structural design, assessment, and control. In practical applications, sampling ...

Abstract: Forming limit diagrams (FLD) have been widely used as a powerful tool for predicting sheet metal forming failure in the industry. The common assumption for forming limits is that the deformation is limited to inplane loading ...

Abstract: Since the forming limit diagram (FLD) was introduced by Keeler, etc., five decades ago, it has been intensively studied by researchers and engineers. Most work has focused on the inplane deformation which is considered as ...

Abstract: A bifurcation analysis of forming limits for an orthotropic sheet metal is presented in this paper. The approach extends Stأ¶ren and Rice's (S–R) bifurcation analysis for isotropic materials, with materials following a ...

Abstract: Doublesided incremental forming (DSIF) is a relatively new dieless forming process which uses two hemispherical ended tools, one on each side of the sheet, moving along a predefined trajectory to locally deform a peripherally ...
