Finite Element Based Study of Radially Elastically Graded Cylindrical Contact against a Rigid Flat under Plane Stress Condition

摘要

This work presents a finite element based analysis of cylindrical contact in plane stress condition against a rigid flat. The elastic modulus of the semi-cylinder is varied radially according to an exponential function. The contact between the semi-cylinder and the rigid flat is considered to be frictionless in nature. Because of the symmetry, a quarter circle is used to model the cylinder and rigid flat surface is modelled using a straight line. The effect of the gradation (quantified by inhomogeneity parameter) on contact behaviors e.g. contact force, contact area, contact stresses etc. of the semi-cylinder are presented and discussed.
