Ductile Failure in High Strength Steel Sheets
Developments in computer-aided engineering and the rapid growth of computational power have made simulation-driven process and product development efficient and useful since it enables detailed evaluation of product designs and their manufacturing processes. In the context of a sheet metal component, it is vital to predict possible failure both during its forming process and its subsequent usag...
متن کاملDuctile Failure and Safety Optimization of Gas Pipeline
Safety and failure in gas pipelines are very important in gas and petroleum industry. For this reason, it is important to study the effect of different parameters in order to reach the maximum safety in design and application. In this paper, a three dimensional finite element analysis is carried out to study the effect of crack length, crack depth, crack position, internal pressure and pipe thi...

properties for erosion protection. Hardness is the most SOLID-particle erosion is a loss of material during repetwidely used property to correlate with the erosion rates of itive impacts of solid particles and is one of the primary materials. For pure metals, some correlation between erosion reasons for fly ash–borne damage of power generation comrate and hardness has been shown.[4] However, se...
متن کاملNumerical Modeling of the Ductile-Brittle Transition
Numerical studies of the ductile-brittle transition are described that are based on incorporating physically based models of the competing fracture mechanisms into the material's constitutive relation. An elastic-viscoplastic constitutive relation for a porous plastic solid is used to model ductile fracture by the nucleation and subsequent growth of voids to coalescence. Cleavage is modeled in ...
