Achieving gradual failure in hybrid composite laminates- progressing from tension to beding (2019)
Presentation / Conference
Jalalvand, M., Idarraga, G., Fotouhi, M., Meza, J., & Wisnom, M. (2019, August). Achieving gradual failure in hybrid composite laminates- progressing from tension to beding. Presented at ICCM22

Most of the progress to-date about achieving gradual failure have been mainly focused on in-plane loading and particularly tension. In many real structural applications, the load is not pure in-plane and is a mix of in-plane and transverse. One of th...

Polyether sulfone interleaved glass/carbon hybrid composite under impact loading (2019)
Presentation / Conference
Fotouhi, S., Clamp, J., Bolouri, A., & Fotouhi, M. (2019, May). Polyether sulfone interleaved glass/carbon hybrid composite under impact loading. Poster presented at Comptest2019

This work presents an attempt to improve the low velocity impact performance of Carbon/Glass hybrid composites by interleaving with tough polyether sulfone (PES) membranes. The hybrid composite was made of a glass/epoxy block that was sandwiched betw... Read More about Polyether sulfone interleaved glass/carbon hybrid composite under impact loading.

Pseudo-ductility of unidirectional thin ply hybrid composites in longitudinal compression (2018)
Presentation / Conference
Suwarta, P., Czel, G., Fotouhi, M., Rycerz, J., & Wisnom, M. (2018, September). Pseudo-ductility of unidirectional thin ply hybrid composites in longitudinal compression. Presented at ASC 33rd Annual Technical Conference

The compression response of unidirectional thin-ply carbon (C) standard thickness S-glass (SG) hybrid composites is presented. Gradual failure up to high strain has been demonstrated for [SG1/(C1/SG1)17] and [SG1/(C2/SG1)17] hybrid configurations. T...

Pseudo-ductile thin-ply composites loaded in tension exhibit a non-linear stress-strain response with a plateau, analogous to yielding in a metal. This provides an alternative means for load redistribution at stress concentrations, giving reduced not... Read More about Reduced tensile notch-sensitivity in pseudo-ductile thin ply composites.

Low velocity impacts on composite laminates can cause a significant amount of delamination that is often referred to as barely visible impact damage (BVID). This damage can cause significant degradation of structural properties, especially the compre...
