Ultimate Load Capacity and Behavior of Thin-Walled Curved-Steel Square Struts, Subjected to Compressive Load
There have been some experimental tests on hollow curved-steel struts with thin-walled square sections, in order to investigate their general behavior, particularly their capacity for bearing differing loads. One set of square tubes are cold-formed into segments of circular arcs with curvature radii, equal to 4000 mm. Different lengths of curved struts are fabricated so as to cover a practical ...
متن کاملElastic Properties and Buckling of Silicon Nanowires
Silicon is the most important material for the electronics industry. Its unique electronic, optoelectronic, thermal, and mechanical properties have made Si an ideal choice for integrated circuits, memory devices, solar cells, and microelectromechanical systems (MEMS). Considering onedimensional (1D) nanomaterials, carbon nanotubes, silicon nanowires, and ZnO nanowires/nanobelts are the three pr...
متن کاملThe Geometric Role of Precisely Engineered Imperfections on the Critical Buckling Load of Spherical Elastic Shells
We study the effect of a dimple-like geometric imperfection on the critical buckling load of spherical elastic shells under pressure loading. This investigation combines precision experiments, finite element modeling and numerical solutions of a reduced shell theory, all of which are found to be in excellent quantitative agreement. In the experiments, the geometry and magnitude of the defect ca...
متن کاملElastic Initial and Post-local Buckling of Profiled through Girders
An experiment investigating the elastic local buckling response of trough girders composed of thin profiled steel sheeting has been undertaken Beam tests were performed to promote initial local buckling in a region of constant moment in the elastic range of structural response. The results of the experiments were compared with an elastic complex semi-analytical finite strip method of analysis, ...
متن کاملThe Effect of Opening on Elastic Buckling of Plates Subjected to Unidirectional Compression Load
This paper has investigated the effect of hole shape, hole size and hole position on elastic buckling of square perforated plates by using the finite element method. According to the effect law of these three geometric factors on buckling bearing capacity, buckling coefficient was obtained by data fitting. The results show that: The plate with circular perforation has the greatest buckling bear...
