Representación de distribuciones tensionales en elementos lineales prismáticos y cilíndricos

Abstract

The  loads  applied  on  a  linear  structural  element  generate  internal  forces  in  the  cross  sections  which,  in turn, result in stresses along the element. The nature, extent and shape of stress distributions are required  parameters  to  compute  the  strength  of  structural  elements  or  machinery  components  in  order  to  its analysis or design. In this work, it is presented a virtual laboratory which allows to obtain different stress distributions  in  an  isostatic  beam,  prismatic  or  cylindrical,  subjected  to  axial  forces,  shear  forces  and bending moments. The virtual laboratory permits a great interactivity, allowing the simulation of various real  situations  in  which  the  user  can  modify  the  magnitude  and  direction  of  acting  loads,  and  also  the boundary conditions of the beam. The ultimate goal of this paper is to present a tool aimed to support the learning and teaching of subjects related to Elasticy and Strength of Materials that are found in bachelor university degrees.
