TL;DR: In this paper, a tri-linear cohesive zone framework is proposed to predict the R-curve for a specimen type whose deformation is shear-dominated (compact tension, CT) from the R -curve of another specimen type (double cantilever beam, DCB).

TL;DR: In this paper, the compressive failure of orthogonal 2D woven composites was investigated using a Four Point Bending (FPB) test setup and the effect of weave architecture and internal geometry.

TL;DR: In this paper, the authors exploit composites with overlapped discontinuities at the ply level to create a significantly non-linear response, due to progressive interlaminar damage under tensile loading.

TL;DR: In this paper, the authors present some evidence which suggests that with the correct hardware and operating procedure/methodology, consistent and high quality carbon-epoxy laminates can be produced, with the possibility of scaling up the process, as demonstrated by the micro and macro-scale mechanical test results.

TL;DR: In this paper, an analytical shear-lag model for the tensile response of discontinuous composites with a "brick-and-mortar" architecture, composed of regularly staggered stiff platelets embedded in a soft matrix, is presented.
