Mechanics of materials

Singularities in bi-materials: parametric study of an isotropic/anisotropic joint

Problems in fracture mechanics are frequently solved in terms of crack tip singularities. Geometries other than cracks also exhibit singular stresses at points such as comers, edges and interfacial joints. Comers occuring in monolayers or…

Stress Singularities Applied to Crack Initiation by Damage of Multimaterial Joints

We consider a multimaterial consisting of dissimilar layers submitted to plane deformations. The elastic stress field at any corner of this kind of joint often exhibits a stress singularity expressed as a function of the r-θ polar coordinates by σ_…

A general methodology for recovering equilibrating finite element tractions and stress fields for plate and solid elements

A recent geometric presentation of a general and efficient methodology for recovering equilibrating tractions and stress fields from 2-D conforming displacement finite element models is reviewed, and further considered in the context of plate…

Singular fields for a bi-material in anisotropic plane elasticity

Using the anisotropic complex potential method, the singular stress field at a corner of a bi-material is derived in the case of complete anisotropy. The singularity exponent is shown to be a root of a 2×2 matrix determinant. The closed-form…

Reinitiation of a crack reaching an interface

We consider here a bi-material made of two layers bonded together by an interface. The specimen is loaded in tension parallel to the interface and the existence of a mode I crack is assumed. The crack initiated in just one layer reaches the…

Size effect in fiber or bar pullout with interface softening slip

The paper analyzes the size effect, which is an inevitable consequence of softening in the relation of interface shear stress and slip displacement between a fiber or reinforcing bar and the surrounding matrix. The problem is simplified as one…
