Effects of forming history on crash simulation of a vehicle

The effects of forming on the crash simulation of a vehicle have been investigated by considering the load paths produced by sheet metal forming process. The frontal crash analysis has been performed by the finite element method, firstly without considering the forming history, to find out the load paths that absorb the highest energy. The sheet metal forming simulations have been realized for each structural component of the load paths and the frontal crash analysis has been repeated by including forming history. The results of the simulations with and without forming effects have been compared with the physical crash test results available in literature.


Effect of CNTs dispersion on electrical, mechanical and strain sensing properties of CNT/epoxy nanocomposites
Tanabi, Hamed; Erdal Erdoğmuş, Merve (Elsevier BV, 2019-03-01)
The remarkable electrical and mechanical properties of carbon nanotubes (CNTs) render CNT-reinforced nanocomposites as potentially attractive materials for strain-sensing and monitoring purposes. The dispersion state of CNTs in polymeric matrix has a significant role on the physical and the mechanical properties of the resulting CNT reinforced nanocomposites. In this study, a series of experiments were designed to investigate the effect of dispersion process parameters and CNT concentration, as well as thei...
Effects of Nanoparticle Geometry and Temperature on the Structural Evolution in FeCo Nanoalloys
Yalçın, Mehtap; Mehrabov, Amdulla; Akdeniz, Mahmut Vedat (Institute of Physics, Polish Academy of Sciences, 2014-02-01)
Effects of nanoparticle size (2.0-6.0 rim) and shape (spherical and cubic) on structural characteristic of atomic ordering processes and order-disorder transformation in B2-type ordered equiatomic-FeCo nanoalloys have been studied by combining electronic theory of alloys in the pseudopotential approximation with Ising-type Hamiltonian site exchange Monte Carlo simulation method. Structural evolutions in amorphous nanopaxticles (2-6 nm) of Fe50Co50 alloy have been utilized via molecular dynamic simulations f...
Experimental Study on the Effects of Winglets on the Performance of Two Interacting Horizontal Axis Model Wind Turbines
Ostovan, Y.; Uzol, Oğuz (2016-10-07)
The focus of this experimental study is to investigate the effects of winglets on the performance of two interacting similar horizontal axis model wind turbines. For this purpose, a downwind winglet is designed and manufactured to be attached to the blade tips of the upstream turbine. A set of wing extensions with the same length as the winglets is also produced to be compared to the winglets. Power and thrust coefficients of both turbines are measured with winglets as well as with wing extensions attached ...
Morphological evolution of voids by surface drift diffusion driven by the capillary, electromigration, and thermal-stress gradient induced by the steady state heat flow in passivated metallic thin films and flip-chip solder joints. II. Applications
Ogurtani, Tarik Omer; Akyildiz, Oncu (AIP Publishing, 2008-07-15)
The void growth and drift motion induced by the combined actions of the phase transformation (evaporation and condensation) and surface drift diffusion driven by the capillary and electromigration forces and thermal-stress gradients are investigated in passivated metallic thin films and flip-chip solder joints via computer simulation using the front-tracking method. As far as the device reliability is concerned, the most critical configuration for solder joint failure occurs even when thermal stresses are l...
Measurement of the cross-section of high transverse momentum vector bosons reconstructed as single jets and studies of jet substructure in pp collisions at root s=7TeV with the ATLAS detector
Aad, G.; et. al. (IOP Publishing, 2014-11-04)
This paper presents a measurement of the cross-section for high transverse momentum W and Z bosons produced in pp collisions and decaying to allhadronic final states. The data used in the analysis were recorded by the ATLAS detector at the CERN Large Hadron Collider at a centre-of-mass energy of root s = 7 TeV and correspond to an integrated luminosity of 4.6 fb(-1). The measurement is performed by reconstructing the boosted W or Z bosons in single jets. The reconstructed jet mass is used to identify the W ...
