Study on the mechanical behavior of high-strength steel wire under the combined action of tension-bending
To study the mechanical behavior of high-strength steel wire under combined action of tension-bending,the stress test of high-strength steel wire is conducted.The stress values under vari-ous axial loads and bending angles are measured.A finite element model is established to simulate the stress distribution of high-strength steel wire under combined action of tensile-bending.The simulation results are in good agreement with the experimental results,verifying the accuracy and rationality of the numerical model.Based on the finite element model,the stress distribution on the surface and cross-section of the high-strength steel wire are further investigated,as well as the influence of bend-ing.The results show that the stress distribution of the high-strength steel wire becomes non-uniform due to the bending angles.For a given axial load,both the stress values and the stress range increase with an increase of the bending angle.The combined action of tension-bending significantly affects the stress variations in the middle and ends of the high-strength steel wire,resulting in considerable stress gradients along both the axial and radial directions in these regions.The effects of the combined action of tension-bending should be given priority consideration in these regions.
