TLDR
In this paper, a finite element method has been employed to study the micromechanics and micro-echanisms in rubber-toughened cross-linked-epoxy polymers.Abstract:
The finite element method has been employed to study the micromechanics and micromechanisms in rubber-toughened cross-linked-epoxy polymers. A two-dimensional plane-strain model has been proposed and has successfully been used to identify the stress fields associated with the dispersed rubbery phase and to simulate the initiation and growth of localized plastic shear-bands running between the rubbery particles. The effects of the microstructure and mechanical properties of the multiphase polymer on the nature and magnitude of the stress fields have also been examined.read more

Rubber-Toughened Epoxies: A Critical Review
TL;DR: A critical review of the field focusing on the important parameters affecting rubber-toughening is presented in this paper, which is classified in five categories including roles of matrix ductility, rubber concentration, blend morphology, particle cavitation, and particle/matrix interface.

Plane strain deformation near a crack tip in a power-law hardening material
James R. Rice,G. F. Rosengren +1 more
TL;DR: In this paper, the authors investigated the C rack-tip strain singularities with the aid of an energy line integral exhibiting path independence for all contours surrounding a crack tip in a two-dimensional deformation field of an elastic material (or elastic/plastic material treated by a deformation theory).

Singular behaviour at the end of a tensile crack in a hardening material
TL;DR: In this paper, a total deformation theory of plasticity, in conjunction with two hardening stress-strain relations, is used to determine the dominant singularity at the tip of a crack in a tension field.

The Physics of Glassy Polymers
TL;DR: In this paper, the authors present the theory of SAXS and its application in the case of glassy phases with phases in internal equilibrium (SAXS-PE) and show that it can be applied to a variety of properties of amorphous polymers.
