On the post-buckling behavior of bilaterally constrained plates
A combined experimental/analytical effort is carried out to elucidate the post-buckling response of bilaterally constrained columns and plates under monotonically increasing edge displacement. Real-time observations of the outward deformation of the plate via the shadow moire technique facilitate deep insight into the behavior of this class of problems. The lateral constraints lead to a sequent...
متن کاملDynamic buckling of morphoelastic filaments.
The equilibrium shapes of biological structures as diverse as plant tendrils and bacterial filaments can be altered by externally imposed stresses of sufficient duration. We study the simplest model for this morphoelasticity--a filament whose intrinsic curvatures relax to the local curvatures--and illustrate its properties in the context of dynamic Euler buckling and writhing. When a thrust or ...
متن کاملUsing FEM for Prediction of Thermal Post-Buckling Behavior of Thin Plates During Welding Process
Arc welding is an important joining process widely used in many industrial applications including production of automobile, ships structures and metal tanks. In welding process, the moving electrode causes highly non-uniform temperature distribution that leads to residual stresses and different deviations, especially buckling distortions in thin plates. In order to control the deviations and in...
متن کاملModeling Elastic and Inelastic, Critical- and Post-buckling Behavior of Bracing Members
An efficient beam element, the modified elastofiber (MEF) element, has been developed to capture the overall features of the elastic and inelastic response of slender columns and braces under axial cyclic loading without unduly heavy discretization. It consists of three fiber segments, two at the member ends and one at mid-span, with two elastic segments sandwiched in between. The segments are ...
متن کاملBuckling Behavior of Substrate Supported Graphene Sheets
The buckling of graphene sheets on substrates can significantly degrade their performance in materials and devices. Therefore, a systematic investigation on the buckling behavior of monolayer graphene sheet/substrate systems is carried out in this paper by both molecular mechanics simulations and theoretical analysis. From 70 simulation cases of simple-supported graphene sheets with different s...
