Finite element analysis of springback in bending of aluminium sheets
Esat, V; Darendeliler, Haluk; Gokler, MI (2002-04-01)
Bending is one of the processes frequently applied during manufacture of aluminium components. The bending operation involves springback, which is defined as elastic recovery of the part during unloading. In manufacturing industry, it is still a practical problem to predict the final geometry of the part after springback and to design appropriate tooling in order to compensate for springback. In this paper, commercially available finite-element analysis (FEA) software is used to analyse bending and springba...

Finite element analysis of cornering characteristics of rotating tires
Erşahin, Mehmet Akif; Ünlüsoy, Yavuz Samim; Department of Mechanical Engineering (2003)
A finite element model is developed to obtain the cornering force characteristics for rotating pneumatic tires which combines accuracy together with substantially reduced computational effort. For cord reinforced rubber sections such as the body plies and breaker belts, continuum elements with orthotropic material properties are used to improve solution times. Drastic reductions in computational effort are then obtained by replacing the continuum elements with truss elements which do not require orientation...
Finite Element Analysis of Laminated Beams Under Transverse Loading
WASTİ PAMUKSUZ, SYEDA NAZLI; Utku, Mehmet (Wiley, 2000-11-01)
Laminated beams fabricated from strips with intermediate adhesive bonding layers are frequently used. The evaluation of the shear and normal stresses in the adhesive layer along the length of the beam is important and both analytical as well as experimental investigations for these stresses have been previously documented. In the present paper, an attempt has been made to compare the analytical shear stress values in the adhesive layer obtained in previous analytical work with those obtained by modelling th...
Finite element analysis of bending operation of aluminum profiles
Penekli, Ufuk; Darendeliler, Haluk; Department of Mechanical Engineering (2008)
Bending process is an important forming process in most industrial fields. Springback and cross-section distortion are commonly faced problems in bending process. Springback behavior of closed and open section beams changes with different parameters such as cross-section type, cross-section dimensions, bend radius and bend angle. For closed sections like tube, the dominating problem is cross-section distortion. The thickness of the tube at intrados (inner surface of tube being in contact with die) increases...
