The numerical analysis of cracks development under nonuniform settlements of a construction

Abstract: Институт гидродинамики им. М.А. Лаврентьева СО РАН, Новосибирск, Россия Новосибирский национальный исследовательский государственный университет, Новосибирск, РоссияРассматривается система из четырех квазилинейных дифференциальных уравнений первого порядка, описывающая плоское пластическое течение материала вне выпуклого отверстия с учетом эффекта инерции. Показано, что система имеет два семейства кратных вещественных характеристик, каждому из которых соответствует один собственный и один присоединенный вектор… Show more

“…At first stage we define tensely-strained state of the construction within the limits of the theory of elastic plates and rectilinear rods. The mathematical statement is defined by equilibrium equations, physical and geometrical relationships and the boundary conditions which which are derived in the matrix form for a middle surface of the plates (overlapping interfloor plates) [1] and rod elements (columns) of the construction [2].…”

“…Border 1 Г is free from loads, and on border 2 Г values of all displacements' components are transferred from the solution in corresponding points of the first problem. The problem decision also was carried out numerically, by means of the finite element method [2] with use of program complex ANSYS. Volume eight nodal finite elements of type SOLID65 with cracking possibility have been chosen.…”
