Quasi-static tests are described for determination of the energy-absorption properties composite crash energy-absorbing segment elements under axial loads. Detailed computer tomography scans failed specimens were used to identify local compression crush failure mechanisms at front. These important selecting materials structures, such as helicopter and aircraft sub-floors. Finite element models processes that could be basis selection future design procedures crashworthy structures.
Test methods are presented to determine failure modes and energy absorption properties of composite crash structural elements from quasi-static tests on chamfered carbon fabric/epoxy tube segment specimens under axial compression loads. High speed film CT scans failed used identify trigger mechanisms, mode evolution at the crush front processes during steady crushing. FE models were developed which could be basis for materials selection design procedures crashworthy structures. These based...
Helicopters typically operate over a large variety of terrains. Designing crashworthy subfloor that can perform efficiently in most impact environments requires the use accurate simulation tools with good confidence modeling approach and representation soft surfaces. The present work investigates accuracy commonly used equations state to numerically model water explicit Finite Element Smoothed Particle Hydrodynamics methods. Both analytical numerical investigations indicated method together...
Composite materials are used extensively in modern helicopter structures to reduce weight. Applications include energy absorption components necessary meet crashworthiness requirements, where composite material can offer higher Specific Energy Absorption (SEA) than traditional metallic materials. However, the constant force absorbers that currently exhibit some limitations, such as under-utilisation of crushing stroke leading inefficient usage and therefore decelerations occupants crash...
