ALGORITHM FOR CALCULATING THE DIRECTIONS OF LAYING TEXTILE REINFORCING FILLER TAKING INTO ACCOUNT THE STRESS STATE OF THE PART

An algorithm and software implementation for calculating reinforcement directions taking into account the stress state of the part have been developed. The initial data for the calculation are the stress values in the part obtained on the basis of finite element modelling. The directions of filling material placement in the nodes of the finite element mesh coincide with the directions of the principal stresses. As a result, two families of curves are formed that coincide with the directions of the maximum and minimum principal stresses. One family is intended for laying the thread in even, and the other in odd layers of the filler. The results of applying the proposed algorithm are given on the example of a model experiencing a complex stress state.
