TL;DR: In this paper, a new ductile fracture criterion (DFC) was developed based on two typical fracture mechanisms - tension fracture and shear fracture by analyzing the morphologies of the fractured surfaces, and discussed through void nucleation, void growth and void coalescence.

TL;DR: In this article, the authors proposed a generalized yield function for describing both asymmetry and Lankford coefficients under the associated flow rule (AFR) framework, in which the linear combination of a series of ξ with odd powers is utilized to model the effect of materials' strength differential (SD) since there are more parameters in the polynomial function of the ξ than the function of ǫ in those existing yield functions.

TL;DR: Wang et al. as mentioned in this paper proposed a thickness prediction model based on the geometrical calculation of intermediate shapes of the formed part and backward tracing of nodal points of the forming tool.

TL;DR: In this article, two heat-assisted incremental sheet forming (ISF) approaches, frictional stir- and electric hot-assisted ISF, have been employed to process the hard-to-form materials in terms of the flexibility and local dynamic heating.
