Foam filling options for crashworthiness optimization of thin-walled multi-tubular circular columns
(Elsevier Ltd., 2018-07-17)
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 ...
Frictional receding contact problem for a graded bilayer system indented by a rigid punch
(Elsevier Ltd, 2018-04-03)
The frictional receding contact problem for two graded layers pressed by a rigid punch is considered in this paper. The punch is subjected to both normal and tangential loads thereby resulting in frictional contact with ...
The sliding contact problem for an orthotropic coating bonded to an isotropic substrate
(Elsevier Ltd., 2018-02-24)
We consider the sliding contact problem of an orthotropic coating/substrate system. The coating/substrate system is pressed by a rigid flat or cylindrical stamp. For the orthotropic coating, the principal material directions ...
Stress analysis and strength prediction of composite laminates with two interacting holes
(Elsevier Ltd, 2019)
In this study, stress analysis and strength prediction were performed for carbon/epoxy laminates with holes in specific orientations using experimental and numerical techniques. The interaction between the holes was studied ...
Evaluation of various multi-cell design concepts for crashworthiness design of thin-walled aluminum tubes
(Elsevier Ltd., 2019)
In this paper, we evaluate various multi-cell design concepts to optimize the crash performances of thin-walled aluminum tubes. The crash performances of the tubes are evaluated by means of two metrics: the crush force ...
Investigation of combined effects of cross section, taper angle and cell structure on crashworthiness of multi-cell thin-walled tubes
(Taylor and Francis Ltd., 2019-04)
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 ...
Design optimization of an automobile torque arm using global and successive surrogate modeling approaches
(SAGE Publications Ltd., 2019-05)
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 ...
Design and Analysis of a Novel Power-Split Infinitely Variable Power Transmission System
(American Society of Mechanical Engineers (ASME), 2019)
In the last few decades, power-split infinitely variable transmission (IVT) systems have attracted considerable attention as they ensure high driving comfort with high total efficiencies, especially in off-highway vehicles ...
The effect of percent foam fill ratio on the energy absorption capacity of axially compressed thin-walled multi-cell square and circular tubes
(Pergamon-Elsevier Science Ltd, 2017)
In this study, the effect of foam fill ratio on the energy absorption capacity of axially compressed thin-walled multi-cell square and circular tubes is investigated. In the experimental study, Aluminum tubes having circular ...
Effect of hole reinforcement on the buckling behaviour of thin-walled beams subjected to combined loading
(Elsevier Sci Ltd, 2017-09)
In this study, the effect of hole reinforcement on the buckling behaviour of thin-walled structures mostly used in aircrafts is investigated under combined loads. A fuselage floor beam with real dimensions is used for the ...
