MARIUS-ALEXANDRU GROZEA, ANTON HADAR Local Nonlinear Problems in Beam Structures Made of Plastics


Abstract:
This work brings to the forefront local nonlinear problems that appear in junctions of beam structures made of plastics, subjected to heavy loads. We also revealed the notions of local problems and heavy loads. These theoretical aspects are explained with the help of two beam structures of various complexity, made of plastic, with local problem. The results are presented as stress maps, maps of mechanical strains, charts with the evolution of the states reached in the structure with the loading steps. We mentioned the situations that require local study; nonlinear problems classification is presented and the methodology for nonlinear calculus is described. Keywords: local problem, beam structure, heavy loads, nonlinearity
