TL;DR: In this article, three analytical models for the investigation of the stiffness and strength of woven fabric composites are presented, i.e., the Fibre undulation model (FDM), Fibre Uniform Model (FUSM) and Multimodal Model (MMM) for modelling the knee stiffness and knee stress in plain weave composites, and a bridging model to simulate the load transfer among interlaced regions in satin composites.

TL;DR: In this article, the upper and lower bounds of elastic stiffness and compliance constants of woven fabric composites are derived, based upon a mosaic-like model as well as the assumptions of constant stress and constant strain.

TL;DR: In this article, basic geometrical and material parameters are identified to characterize the structure of hybrid fabrics and analysis of the elastic behavior is made based upon a mosaic model and the fabric composite.

TL;DR: In this paper, a simple analytical model for the initial stiffness of the corrugated composites is developed, and the predictions are compared with the experimental results, and some improvements, installing of stiff rod and flexible rubber, are attempted for the creation of smooth aerodynamic surface and the improvement of stiffness.

TL;DR: In this paper, a special measurement system using a non-contact electro-optical extensometer to measure hole elongation is proposed during static tensile testing, the response of bearing damage was monitored by acoustic emission measurement Several specimens were observed by means of soft X-ray radiography and SEM at different loading levels to assess internal damage.
