Abstract: In the current research, the role of nano-sized alumina on deformation and fracture mechanism of Poly Methyl Methacrylate (PMMA) was investigated. For this purpose, PMMA matrix nanocomposite reinforced with different wt% of alumina (i...

. Microscopic evaluation proves an increase in SiO2 content causes to change the fracture mechanism....

This paper devoted to analysis of cracked truss type structures. For this purpose, five common cracked bar finite elements, according to the laws of fracture mechanics, are first introduced and verified. Parameters which affect the stiffness matrix...

A novel finite element with a central crack is proposed for fracture applications. The introduced element is applicable in 2D problems. The crack is modeled by an additional flexibility matrix based on fracture mechanics. Among the topics discussed...

This paper deals with the analysis of cracked skeletal structures. For this purpose, a beam-column element

with an edge crack is applied. This element is formulated based on the laws of linear fracture mechanics. Static behavior, natural...

resistance of dam.

Recently, fracture mechanics has been advocated in papers, as an alternative means to assess dam safety. In this study, linear elastic fracture mechanics concepts were applied to assess the crack stability in ZAVIN Concrete...
