TL;DR: In this paper, the authors reported that glass fiber strength and elongation at break decreased significantly after hygrothermal ageing, which is the major mechanism responsible for the reduced performance of GFRP composites.

TL;DR: In this paper, three composite lay-ups were designed by altering the position of the carbon fiber ply, i.e., pure flax/polypropylene laminates, Laminates with flax ply at the surface and Laminations with the carbon ply at surface.

TL;DR: In this article, an integrated impact localization scheme is proposed and validated based on the arrival time obtained by wavelet transform (WT) analysis of signals received by dynamic strain gauges, triangulation localization technique together with a proposed hybrid particle swarm optimization (PSO) and GA algorithm.

TL;DR: In this article, a real-time non-destructive testing method is proposed to evaluate the transverse cracking in cross-ply laminates, which is one of the most common initial failure modes of composites and has detrimental effects on the structural integrity.

TL;DR: In this paper, a modified Taylor-based nonlocal theory of plasticity is proposed to quantify the individual contributions of size-dependent geometrically necessary dislocations (GNDs) when the size of particles is on the order of micron.
