Boundary Element Analysis of Three-Dimensional Exponentially Graded Isotropic Elastic Solids
(Tech Science Press, 2007)
A numerical implementation of the Somigliana identity in displacements for the solution of 3D elastic problems in exponentially graded isotropic solids is presented. An expression for the fundamental solution in ...

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 ...

Green's Function Evaluation for Three Dimensional Exponentially Graded Elasticity
(Wiley, 2008)
The numerical implementation of the Green's function for an isotropic exponentially graded three dimensional elastic solid is reported. The formulas for the nonsingular `grading term' in this Green's function, originally ...

Microscopical observations of interface cracks from inter-fibre failure under compression in composite laminates
(Elsevier, 2018-07)
Matrix/inter-fibre failure is characterized by the appearance at the fibre–matrix interfaces of small debonds that can progress along them until reaching a certain extension, then changing their orientation to kink towards ...

On the optimal choice of fibre orientation angle in off-axis tensile test using oblique end-tabs: Theoretical and experimental studies
(Elsevier, 2019-07)
Shear strength evaluation in composite materials still remains a not fully solved problem. One of most promising proposals to characterise a material in shear by means of a simple tensile test is the off-axis tension test ...
