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 ...

Comparison of the shear behavior in graphite-epoxy composites evaluated by means of biaxial test and off-axis tension test
(De Gruyter Open Ltd, 2021-01)
Characterization of shear behavior in composite materials remains a not fully solved problem. In the last fifty years, many different approaches have been proposed to solve this problem (rail shear, thin-walled tube torsion, ...

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 ...

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 ...
