Aircraft structural safety is achieved by using different safety measures such as safety and knockdown factors, tests and redundancy. Safety factors or knockdown factors can be either explicit (e.g., load safety factor of ...

There is an increasing trend in using aluminum foam-filled columns in crash management systems due to theirlight weight in automotive industry. The main goal of this study is to optimize the crashworthiness of aluminumfoam-filled ...

The design of lightweight automotive structures has become a prevalent practice in the automotive industry. This study focuses on design optimization of an automobile torque arm subjected to cyclic loading. Starting from ...

Tail modeling method is a popular method for predicting reliability of highly safe mechanical systems. In classical tail modeling, only the limit-state values that belong to the tail part are used in tail model fitting, ...

Crash box design has a substantial importance to reduce the fatalities in a frontal crash. In this study, four different types of multi-cell tubes, namely straight-circular, straight-square, tapered-circular and tapered-square ...

When the limit state function (or performance function) of a structure can be written as the difference of a capacity function and a response function that are expressed in terms of independent sets of random variables ...

Radial basis functions (RBFs) are approximate mathematical models that can mimic the behavior of fast changing responses. Different formulations of RBFs can be combined in the form of an ensemble model to improve prediction ...

Design and analysis of modern engineering systems are complicated, mostly relying on computational analyses codes and hence often computationally expensive. Meanwhile, improved computer-aided design and numerical simulation ...

In this paper, the effects of introducing lateral circular cutouts on crash performances of tapered thin-walled tubes are explored within a simulation-driven surrogate-based multi-objective optimization framework. The crash ...

Due the fact that aircraft structures work in an environment with lots of dynamic forces, it is of vital importance to perform a dynamic analysis to understand dynamic characteristics of aircraft in that specific environment. ...
