An Augmented Treatment of Isogeometric Contact Analysis

摘要：

　　In penalty-based contact treatment,contact pressure is described as: p = ?g(g is the gap between the contact surfaces and is the normal penalty parameter).This lead to a simple implementation,but however,its difficult to choose a suitable value of the penalty parameter.The usual way is adopting an appropriate multiple of the modulus of elasticity.This paper evaluate an augmented method for isogeometric contact problem which can alleviate the influence of parameter.As an example a Hertz contact problem is presented,and the results are compared with Hertz theory.
