A MATHEMATICAL CLOSURE MODEL : Arrest of a crack in Infinite Slit in Elastic Plastic Media
Journal Title: Advance Research Journal of Multidisciplinary Discoveries - Year 2017, Vol 14, Issue 6
Abstract
In this paper, the problem of a finite hairline straight crack weakening an infinite homogeneous elastic perfectly-plastic plate is considered. The plate is subjected to uniform constant unidirectional tension which is applied to it at infinite boundary. Consequently, face of crack open in mode-I type deformation farming plastic Zones ahead of the tip of the crack. To stop the crack form further extension rims of the plastic zones are subjected to normal cohesive cubically varying yield point stress distribution. To visualize the entire physical picture of the problem, problem is considered in two components which are superimposed afterwards to get the solution of original problem. Wester Gard technique is problem. Wester Gard technique is applied to solve the problem. Variation of load required for the closure of plastic zones is studied with respect to the affecting parameters. Results obtained are analyzed and graphically reported.
