Stability of moving fronts under Griffith criterion: a computational approach using integral equations and domain derivatives
Abstract
Consider a linearly elastic body Ω ∈ R 3. Its external boundary is divided into two complementary parts S u (supporting prescribed displacements: u = ū) and S t (supporting prescribed tractions: σ. n = t). Besides, a crack (described by an open surface S across which the displacement is discontinuous: ϕ = u + — u - denotes the crack opening displacement (COD)) is embedded in Ω.
