BOUNDARY INTEGRAL FORMULATION OF FRICTIONLESS CONTACT PROBLEMS BASED ON AN ENERGETIC APPROACH AND ITS NUMERICAL IMPLEMENTATION BY THE COLLOCATION BEM

A unified methodology to solve problems of frictionless unilateral contact as well as adhesive contact between linear elastic solids is presented.This methodology is based on energetic principles and is casted to a minimization problem of the total potential energy.Appropriate boundary integral forms of the energy are defined and the quadratic prob

From 1980s, electromagnetic prospecting is an integral component of geophysical techniques for oil and gas exploration in many regions of the Russian Federation.Electromagnetic methods are used at all stages of geological exploration, including reconnaissance, discovery, prospecting and appraisal, and economic mining.In oil and gas exploration, the

Acute Tuners central nervous system injuries are among the most common causes of disability worldwide, with widespread social and economic implications.Motor tract injury accounts for the majority of this disability; therefore, there is impetus to understand mechanisms underlying the pathophysiology of injury and subsequent reorganization of the mo

This paper investigates the Cucker-Smale flocking control problem of leader-follower multiagent systems in the presence of periodic intermittent communication, in which networked agents update the states by communicating with their neighbors during active periods and remain stable during dormancy periods.A distributed Tuners update algorithm that r

Interstitial lung diseases (ILD) are a spectrum of disorders often complicated by pulmonary hypertension (PH) in its course.The pathophysiologic mechanism of WHO group 3 PH is different to other forms of PH.The advent of PH is a harbinger for Me Fall Outerwear adverse events like mortality and morbidity, implying that the PH component of disease ex
