To protect passengers, large aircraft are equipped with multiple mechanisms to absorb impact energy during a crash. However, light aircraft rely only on the cabin structure to withstand the compression and energy generated during a crash. This study performed a topology optimization analysis on the model structure by using Abaqus/optimization and used strain energy as the objective function and...

This paper presents a procedure to optimize a conceptual ship side structure from a crashworthiness point of view. As an example, this procedure is presented for a chemical or product tanker. A particle swarm optimization algorithm is used for the procedure. The classification society compliance of the conceptual design is checked through service loads that are applied to the ship’s hull girder...

The crashworthiness of helicopter fuel tank is vital to the survivability of the passengers and structures. In order to understand and improve the crashworthiness of the soft fuel tank of helicopter during the crash, this paper investigated the dynamic behavior of the nylon woven fabric composite fuel tank striking on the ground. A fluid-structure interaction finite element model of the fuel ta...

OBJECTIVE Child dummies and injury criteria used in automotive crashworthiness environments are based on scaling from the adult and/or between children of different ages. Cartilage-to-bone ossification, spinal canal and joint developments of the spine, and strength attainments do not grow linearly from birth to maturity. Though this is known to medical professionals, age-based quantitative anal...

As a form of transport, rail has always maintained lower accident levels than its counterparts, the car and the airplane. The railway industry, however strives for still better safety measures to be implemented – a fact which intensifies with each accident that occurs. In the last years the continuous developments in technology, computer modeling capabilities and know-how have opened up various...

The use of metallic materials in automotive industry leads to increasing fuel consumption and cost, so trends are starting lighter cheaper materials. In applications, fibers used composites because they stronger, stiffer, than bulk materials, can achieve higher energy absorbing compared purpose this work is study the potential utilization natural crash applications. experimental procedures (the...

While the automotive industry is striving for reduction of car body weight to increase fuel efficiency and reduce CO2 emission without compromising safety crashworthiness vehicles, a new generation advanced high strength steels (AHSS) have emerged as excellent candidates meet these requirements. However, their integration into structure associated with welding-related problems. This research ut...
