Longitudinal Bending of Polymer Rods with Account Taken of Creep Strains and Initial Imperfections

Abstract

An investigation was made of the loss of stability of polymer rods exposed to disturbances in the form of camber of the rod and eccentricity of load application. At present, polymeric materials are being used not only as fencing constructions and as constructions of 'secondary' value but also as bearing elements. Polymer rods for the strengthening of suspended constructions are an example. These rods undergo both elongation and compression.

Calculation of a three-layer plate by the finite element method taking into account the creep of the filler

“…Using (8), we can express from (7) the growth rates of creep strains: This method is also used in [4][5][6][7][8][9]. The following boundary conditions were assumed: Fig.…”

Axisymmetric bending of a circular three-layer plate taking into account creep

“…To determine the creep deformations, the Euler method can be used. A detailed stepwise calculation procedure is described in [5][6][7][8][9][10].…”

Features of compressed rods calculations with account of initial imperfections and creep effects

“…Buckling analysis of compressed rods considering creep effects has been touched on many articles, including [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. The articles [1][2][3] outline the solution to this problem using the finite difference method. In the works [4][5] the energy method in the form of Ritz-Tymoshenko is applied.…”
