Characteristics of cars, such as mass and age, play a significant role in crash severity, but their effect are difficult to quantify because of the great number of factors altering the outcome of a real world accident. In order to focus on the crashworthiness of cars, we examine risk factors of severity suffered by the drivers involved in two-car accidents recorded by the police between 1996 an...

Numerous collision conditions can occur during ship operations, resulting in various consequences that require specific consideration for optimizing crashworthiness design. Existing studies have investigated design structures; however, they often focus on single working and do not comprehensively consider the diverse scenarios encountered operations. To overcome this drawback, paper proposes a ...

Vehicle frontal crashworthiness analysis is an important topic in the field automotive community, as it relates to legislative requirements. Frontal crash models contain a large number of elements and therefore present high computational cost, especially when performing structural performance optimisations. A new numerical methodology proposed this paper with aim increase computation speed by i...

Due to their lightweight, porous and excellent energy absorption characteristics, foam honeycomb materials have been widely used for filling absorbing devices. For further improving the performance of novel tube proposed in our recent work, nonlinear dynamics software Abaqus was firstly establish verify simulation model aluminum-filled tube. Then, crashworthiness honeycomb-filled tubes, foam-fi...
