Webb11 apr. 2024 · We derive a dimension-reduction limit for a three-dimensional rod with material voids by means of $Γ$-convergence. Hereby, we generalize the results of the purely elastic setting [57] to a framework of free discontinuity problems.

In modern production engineering, the elastic-plastic bending and the stamping of strips, various beam sections and sheets, has been extensively employed in the forming of large metal members of structures, such as the skins of pressure vessels, … Webb4. The geometry of the overall member is such that bending not buckling is the primary cause of failure. 5. Elastic limit is nowhere exceeded and ‘E' is same in tension and compression. 6. Plane cross - sections remains plane before and after bending. Let us consider a beam initially unstressed as shown in fig 1(a). trumpet noises in the sky
