Processing Steps

A theory and a mathematical model are developed for calculating the parameters of the strain-stressed state at the stages of pre-bending, calibration, straightening and bending of the straightened section, taking into account the strengthening of the billet on a roll machine. By CAD/CAE modeling the strains, stresses and forces acting on the billet from the rolls are investigated. Criteria for the formation of cracks, low accuracy and excessive springing of the billet after these processing steps are determined, recommendations are given for their elimination. Keywords billet, sheet stamping, bending, roll machine, pre-bending, calibration, straightening, bending of the straightened section, CAD/CAE modeling. [email protected]

Formation Of Cracks

It is proposed a computational model of spatial formation of cracks in reinforced concrete constructions under the action of torsion with bending, based on working assumptions and constructed equations. The physical interpretation of the solution is that it allows to search for generalized minimum load, which corresponds to the formation of the first crack and the spatial coordinates of the point of its formation.
