An Energetic Approach to Rate Independent Delamination with Cohesive Contact - An SGBEM Implementation

Abstract:

Article Preview

A mathematical model for analysis of contact delamination problems has been developed and implemented into the program Matlab by means of the Symmetric Galerkin Boundary Element Method (SGBEM). The SGBEM numerical algorithm enables to exploit an energetic formulation which governs interface rupture. A rate-independent model of the delamination process is obtained, considering an interface damage variable. A numerical algorithm has been proposed to provide maximallydissipative local solution which yields numerically stable time-discretization. The developed 2-dimensional sample example of mathematical model demonstrates the model behaviour and its suitability in many aspects of engineering practise.
