Temper rolling or skin pass rolling is one of cold rolling processes composed of a horizontal pass cold rolling mill stand. In this process, the thick strip is subjected to very light reduction (0.5–4%) in thickness in the presence of high friction amplitudes. One of the basic parameters of strip rolling processes is temper rolling force. A new rolling force model has been proposed for temper r...

Prediction of soft tissue failure may yield a better understanding of the pathogenesis of arterial dissection and help to advance diagnostic and therapeutic strategies for treatment of this and other diseases and injuries involving the tearing of soft tissue, such as aortic dissection. In this paper, we present computational models of tear propagation in fibre-reinforced soft tissue that underg...

Combining with <i>in situ</i> nanomechanical testing system and video module of scanning electron microscope, the nanoindentation is performed to study peeling-tearing behavior two-dimensional material van der Waals heterostructures. After MoS<sub>2</sub> nanosheets prepared by chemical vapor deposition are assembled into MoS<sub>2</sub>/SiO<sub>2</s...

Woven cloth can commonly be seen in daily life and also in animation. Unless prevented in some way, woven cloth usually frays at the edges. However, in computer graphics, woven cloth is typically modeled as a continuum sheet, which is not suitable for representing frays. This paper proposes a model that allows yarn movement and slippage during cloth tearing. Drawing upon techniques from textile...

An algorithm suitable for numerical solution of linear eigenmode problems in resistive magnetohydrodynamics MHD and two-fluid MHD models without prior approximations is presented. For these plasma models, sets of equations suitable for numerical solution are derived and the details of the algorithm of this solution are given. The algorithm is general and is suitable for solution of boundary eig...

Tearing a thin sheet by forcing a rigid object through it leads to complex crack morphologies; a single oscillatory crack arises when a tool is driven laterally through a brittle sheet, while two diverging cracks and a series of concertinalike folds forms when a tool is forced laterally through a ductile sheet. On the other hand, forcing an object perpendicularly through the sheet leads to radi...

PURPOSE To determine the success rate of conventional dacryocystorhinostomy (DCR) and endoscopic DCR performed in patients with acute dacryocystitis. METHODS Records of patients with acute dacryocystitis and operated during 2007-2008 were reviewed. Patients who completed a follow-up of 60 months were included in our study. Demographic characteristics, surgery types, success rate, and follow-u...

Material and methods. The study assessed 2 types of chains. The first phase of the study evaluated 1) the tensile strength of the chains; and 2) elongation at the time of tearing in an environment outside of the oral cavity (without exposition). The second phase of the study evaluated 1) permanent deformation after stretching; 2) elongation at the time of tearing; and 3) the tensile strength of...
