Premature failures in standard test specimens with composite materials induced by stress singularities in adhesive joints
(Elsevier, 2020-03)
This work presents three examples of standard test configurations, involving composite materials, where the presence of stress singularities induced by adhesive joints causes premature failures leading to underestimated ...

Discontinuous quarter-point boundary elements revisited: Computation of T-stress in two-dimensional cracked components
(Elsevier, 2023-12)
This paper analyzes the use of discontinuous quarter-point quadratic elements in a dual or hypersingular boundary element context to compute the T-stress for cracked 2-D isotropic components. The performance of this ...

A powerful matrix formalism for stress singularities in anisotropic multi-material corners. Homogeneous (orthogonal) boundary and interface conditions
(Elsevier, 2022-06)
A computational code based on a semianalytic procedure for the determination of the characteristic exponents and the singular stress and displacement fields in multi-material corners is developed. Linear elastic anisotropic ...
