Ductile or Partial Ductile Mode Machining of Brittle Materials
This paper reports ductile or partial ductile mode machining of silicon, glass and some advanced ceramics. Results are presented using scanning electron micrographs of the machined surfaces. Grinding and lapping operations using inexpensive machine tools could produce ductile streaks on surfaces of these brittle materials under good conditions. Manufacture of spherical glass lenses by the fract...
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...
متن کاملDynamic Failure of Metallic Cellular Materials
The quasi-static and dynamic compressive behavior of open-cell foams, textile cores, and pyramidal truss cores were investigated using a combination of experimental apparatus. Quasi-static tests were performed using a miniature loading stage and a Kolsky bar apparatus was used for intermediate deformation rates. For high deformation rates, a gas gun was employed. Optical observations of the sam...
متن کاملSimulation of Crack Growth in Ductile Materials
During crack growth of real materials, the total energy released can be partitioned into elastic and dissipative terms. By analyzing material models with mechanisms for dissipating energy and tracking all energy terms during crack growth, it is proposed that computer simulations of fracture can model crack growth by a total energy balance condition. One approach for developing fracture simulati...
متن کاملFailure Criteria Analysis of Laminate Composite Materials
This paper deals with the development of a numerical simulation methodology for estimating damages in laminate composite materials caused by a low-speed impact. Experimental tests were performed on laminate plates reinforced with woven carbon fibers and epoxy resin. Three thickness plates were evaluated. The impact loads were transversal and punctual. Two lamina failure criteria were evaluated....
