Discrete element analysis of the punching behaviour of a secured drapery system: from laboratory characterization to idealized in situ conditions

Abstract In this work, the mechanical response of a steel wire mesh panel against punching load is studied starting from laboratory test conditions and extending results to field applications. Wire meshes anchored with bolts plates are extensively used in rockfall protection slope stabilization. Their performances evaluated through tests, but constraints, geometry loading may strongly differ situ leading incorrect estimations strength mesh. discrete element method simulate After validation numerical model experimental data, behaviour an investigated order obtain more realistic characterization conditions. The dimension element, its position, anchor plate size spacing varied, providing analytical relationships able predict different Furthermore, aspect ratio analysed showing existence optimal value. study can provide useful information practitioners for designing secured drapery systems, as well assessment their safety
