| Abstract Scope |
In this work, finite element simulations of Mode I fracture in Zr-based porous bulk metallic glasses (BMGs) having various porosities (f = 0%,1%,2%,3%,4%,5%, and 7%) are carried out. It was found that porous BMGs have higher fracture toughness as compared to monolithic BMGs. The peak fracture toughness (35.52 MPa√m) was observed in the case of porous BMG having an optimum value of 2% porosity, which is about 28% tougher than the monolithic BMG. The porous BMG having 2% porosity exhibits a rising resistance curve (indicating toughening effect of pores) with propagation toughness as high as 54.7 MPa√m. |
