Tube hydroforming (THF) process is used to produce the complex components from the initial cylindrical tubes. In this paper, T- shape component was formed using a tube hydroforming machine and the residual stresses of hydroformed tube was determined by hole drilling method. Subsequently, the thickness distribution and residual stresses of final tube were investigated using experimental and fini...

In this paper, we present a discrete approach to 2D statistical shape models construction. An object is modeled in terms of landmark points on its contour. An optimized process of intrinsic discrete properties computes then curvilinear position, curvature and normal vector for each point. The approach uses after a dynamic programming process to match points of different shapes. By identifying m...

rndetermination of rock mass deformation modulus is very important in different projects, especially in civil and mining engineering works. in-situ measurements such as dilatometer, plate load and flat jack methods may be applied to determine the deformation modulus. however, these methods are very expensive and time- consuming. analytical methods are very useful approaches which can also be us...

This thesis describes a system for extracting three-dimensional models from two-dimensional images over the restricted domain of frontal images of human faces. A three-dimensional face model template is fit to a three-dimensional digitizations of a set of training subjects. The standard-form models allow different subjects to be treated in a uniform manner. The particular template model chosen ...

a 5th order shear deformation theory considering transverse shear deformation effect as well as transverse normal strain deformation effect is presented for static flexure   analysis of simply supported isotropic plate. the assumed displacement field accounts for non-linear variation of in-plane displacements as well as transverse displacement through the plate thickness. the condition of zero ...
