Elastoplastic Behavioranalysis of Clamped Circular Perforated Thin Plates
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 2
Abstract
Elastoplastic dimensioning is an important step in the design of Tubesheets. Indeed, they must be as thin as possible in order to reduce the internal temperature gradients and the risks related to thermal fatigue, and at the same time, to reduce the industrialization costs related to the material and perforations. Several studies have been developed with the aim of finding an elastoplastic model of calculation which is the most appropriate in analytical theor1,2 or using finite element method. The aim of this work is, then to propose a 2D Typical model for the numerical simulation of the circular clamped perforated thin plates behavior in the elastic and elastoplastic domains. Unlike the majority of the literature calculations that are based on the equivalent solid plate model,this Model is based on the real geometry of plates and takes into account different perforation distribution patterns and ligament factors and it is then validated by experiments1 .
