laser forming is a modern process which is mainly used for forming metals. different lasers are used in this regard that includes nd: yag and co2. in this study, forming bi-layer sheets of aluminum/ceramic by laser was investigated. furthermore, effect of uniform and gaussian heat flux distribution in different power, velocity, and beam diameters on bending angle was studied. fem simulation ind...

in this paper, a numerical method is developed for solving a linear sixth order boundaryvalue problem (6vbp ) by using the hyperbolic uniform spline of order 3 (lower order). thereis proved to be first-order convergent. numerical results confirm the order of convergencepredicted by the analysis.

Recent experiments in various cell types have shown that two-dimensional tissues often display local nematic order, with evidence of extensile stresses manifest the dynamics topological defects. Using a mesoscopic model where tissue flow is generated by fluctuating traction forces coupled to order parameter, we show resulting can spontaneously produce and an internal stress. A key element assum...

A numerical analysis of the limit state for solids, with an adequately described structural geometry, is often a computationally demanding task, and there need effective method. The existing solid elements Finite Element Limit Analysis (FELA) are either expensive or require stress cutoff yield surface triaxial states. This paper presents partially mixed lower bound tetrahedral constant element ...

This investigation arises from identifying a problem within the territory of Tena canton, located in north Ecuadorian Amazon, biodiverse area at natural and cultural level but that suffers waste tourist at-tractions, especially Santa Rosa sector, which worsens due to absence adequate infrastructure, affecting well-being its inhabitants, who would imminently benefit rescue their culture generati...

A novel mixed-mode cohesive law derived from a potential function is presented. The formulated using physical parameters that can be extracted any fracture mechanics test capable of providing R-curves in terms the J-integral as normal and tangential end-openings. proposed able to describe behaviour composites with large process zones, including fibre bridging. As such, it describing both crack ...

  In this paper, we present some important dynamical concepts on uniform space such as the minimal systems, shadowing, and strong shadowing. We explain definitions theorems definition expansive, weak generator, proof of for them. prove that if  be a homeomorphism compact  then  has shadowing only has so also show  and two homeomorphisms spaces ,  is conjugacy from ...
