In this research, the variation of ultimate bearing capacity, failure mechanism and deformation pattern of soil beneath two closely square footings have been studied using numerical methods. It is assumed that the adjacent footings are constructed on the surface of sand. The presented numerical analyses are based on explicit-finite-difference code, FLAC3D. The elasto-plastic behavior of soil is...

Flame bending process is one of the forming processes of steel plates. During this process, plate is formed with heating by gas torch flame followed by controlled cooling along specified paths. Considering simple tools used in the process, it is a popular and economical forming method. At present, this process is manually done on the basis of skilled technician’s experience. Experimental and ...

With the increasing complexity of photo-realistic scenes, the question of building and placing objects in three-dimensional scenes is becoming ever more di cult. While the question of placement of rigid objects has captured the attention of researchers in the past, this work presents an intuitive and interactive scheme to properly place deformable objects with the aid of free-form deformation t...

We examine the large deformation elastic response of the spectrin network in a human red blood cell (RBC) on the basis of molecular-level constitutive laws. These formulations are shown to be consistent with the predictions of continuum level models for the hyperelastic deformation of RBC, and are compared with recent experimental studies of whole-cell deformation using optical tweezers stretch...

ca2 (continuum analysis, 2- dimensional) is a computer program developed by the author. ca2 can solve a variety of complex geotechnical problems using explicit finite difference method. in this paper, an introduction will be given to the theoretical and numerical basis of the program and the capability of the code will be shown by solving a few interesting nonlinear and transient problems. fina...

interferometric synthetic aperture radar (insar) technique is valuable tool in monitoring crustal deformation due to its large spatial coverage and high spatial resolutions. in this paper, the intersiesmic crustal deformation occurred before earthquake on august 2012 in ahar-varzegan located in north-west of iran is studied using persistent scattering interferometry. the psi algorithm used in t...
