Open Archive Toulouse Archive Ouverte (oatao) Experimental Investigation on Mean Crushing Stress Characterization of Carbon–epoxy Plies under Compressive Crushing Mode

A challenge in numerical simulation of crashworthiness study is to be able to predict the crush damage modes, their evolution during crushing and the energy absorption in any composite structure from elementary material characterisation data. Therefore, it is important to know the behavior of one ply subjected to crushing load, and especially to determine the mean crushing stress that could be ...

Numerical Investigation on the Reference Crushing Stress of Granular Materials in Triaxial Compression Test

Particle crushing dominates the deformation behaviour of granular materials under significantly high compressive and shear stress. A proposed constitutive model has been verified to predict crushing behaviour of granular materials with different crushability and adopted one kind of reference crushing stress. It is noted that no positive dilatancy of granular material in triaxial test occurs onc...

Experimental and Numerical Simulation Investigation on Crushing Response of Foam-Filled Conical Tubes Stiffened with Annular Rings

In this paper, crashworthiness characteristics of conical steel tubes stiffened by annular rings and rigid polyurethane foam are investigated. For this purpose, wide circumferential rings are created from the outer surface of the conical tube at some determined areas along tube length. In fact, this method divides a long conical tube into several tubes of shorter length. When this structure is ...

Crushing injuries to the skull; clinical and experimental observations.

Severe crushing injuries of the head are often fatal, but in those patients who survive this form of injury the absence or slight degree of concussion is usually a striking feature of the clinical picture. Even though the skull may be fractured and the cranial nerves injured, the patient often remains fully conscious. This clinical observation led one of us (W.R.R.). with Denny-Brown (1941) to ...

Numerical Study on the Crushing Behavior of Square Tubes Under Three Dimensional Oblique Loading

This study aims to numerically investigate on the crashworthiness of thin-walled square tubes by consideration of 3-D oblique loading. In this type of loading, direction of loading is defined by using two spatial angles relative to the position of the tube. To this aim, finite element (FE) analysis is employed to simulate the loading for 8 different numerical models with different loading orien...
