Interface effects on the strength and ductility of bimodal nanostructured metals

Microstructure‐Property Relations in the Tensile Behavior of Bimodal Nanostructured Metals

“…[35][36][37][38] By CFEM, the microcrack initiation and propagation can be vividly tracked; [35][36][37][38] the interface effects can also be revealed. [34,38] Comparing with the 2D numerical simulations, the 3D numerical simulations have been verified to have superiority in investigating the fracture behavior of materials. [32,38,39] However, to our best knowledge, no systematic numerical investigation via the 3D CFEM has been reported to address the effects of the distribution of CG inclusions together with the interfaces on the fracture behavior of bimodal NS metals.…”

“…[34] The overall strength and ductility is saturated when the cohesive strength of interfaces surpasses a certain level. [34] It turns out that the CFEM is feasible to investigate the fracture behavior of engineering materials. [35][36][37][38] By CFEM, the microcrack initiation and propagation can be vividly tracked; [35][36][37][38] the interface effects can also be revealed.…”

“…Recently, the effects of interfaces together with the shape and distribution of CG inclusions in the bimodal NS Cu have been well investigated by 2D cohesive finite element method (CFEM) . The overall strength and ductility is saturated when the cohesive strength of interfaces surpasses a certain level . It turns out that the CFEM is feasible to investigate the fracture behavior of engineering materials .…”

“…Nonetheless, interface effects have not yet been involved in these studies. Recently, the effects of interfaces together with the shape and distribution of CG inclusions in the bimodal NS Cu have been well investigated by 2D cohesive finite element method (CFEM) . The overall strength and ductility is saturated when the cohesive strength of interfaces surpasses a certain level .…”
