Aircraft Structural Safety : Effects of Explicit and Implicit Safety and Measures Uncertainty Reduction Mechanisms 

Acar, Erdem (University of Florida, 2006)
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 ...

Yüksek Emniyetli Mekanik Sistemlerin Yanıt Yüzey Destekli Kuyruk Modelleme Yöntemiyle Güvenilirlik Tahmini 

Acar, Erdem (Gazi Üniversitesi, 2018)
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, ...

Investigation of combined effects of cross section, taper angle and cell structure on crashworthiness of multi-cell thin-walled tubes 

Altın, Murat; Kılınçkaya, Ümit; Acar, Erdem; Güler, Mehmet Ali (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 ...

A reliability index extrapolation method for separable limit states 

Acar, Erdem (Springer, 2016-05)
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 ...

Simultaneous optimization of shape parameters and weight factors in ensemble of radial basis functions 

Acar, Erdem (Springer, 2014-06)
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 ...

Optimum crashworthiness design of tapered thin-walled tubes with lateral circular cutouts 

Tastan, A.; Acar, Erdem; Güler, Mehmet Ali; Kilinckaya, U. (Elsevier Sci Ltd, 2016-10)
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 ...

Enhancement of quality of modal test results of an unmanned aerial vehicle wing by implementing a multi-objective genetic algorithm optimization 

Pedramasl, Nima; Sahin, Melin; Acar, Erdem (Elsevier France-Editions Scientifiques Medicales Elsevier, 2017-12)
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. ...
