The Hashin criterion is one the most popular failure criteria for fibre reinforce composites. It is critically appraised in this paper. The most significant feature of the criterion is failure modes introduced and the assumption that failure is deter... Read More about A critical appraisal of the Hashin failure criterion.

Characterisation of 3D woven textile composites in presence of minor weft tow undulations and cross-section variations (2024)
Journal Article

Weft tows in 3D woven composites are commonly approximated as perfectly straight, but their undulations are inevitable in reality, although the extent of undulations in the weft tows is not as pronounced as in the warp tows. Such minor undulations in... Read More about Characterisation of 3D woven textile composites in presence of minor weft tow undulations and cross-section variations.

A failure criterion for genuinely orthotropic materials and integration of a series of criteria for materials of different degrees of anisotropy (2024)
Journal Article

Existing failure criteria for orthotropic materials are subject to an underlying assumption which cause contradictions when applied to genuinely orthotropic materials that are significantly anisotropic in elasticity as well as in strengths. For such... Read More about A failure criterion for genuinely orthotropic materials and integration of a series of criteria for materials of different degrees of anisotropy.
