Buckling Capacity Optimization of Stiffened Rectangular Plate under Uniform Normal Compression
The stiffened rectangular plate was usually adopted in the blast airtight doors. In order to improve the buckling capacity of stiffened rectangular plate under uniform normal compression, the optimization model of stiffened rectangular plate was set up based on APDL and ANSYS commands, and the sequential linear programming method was executed to optimize the thickness of plate and the sizes of ...
متن کاملBuckling of Ge nanowires under uniaxial compression
Molecular dynamics simulations are performed to investigate the buckling properties of [100]-, [110]-, [111]-, and [112]-oriented single-crystalline germanium nanowires under uniaxial compression. The effects of simulation temperature, strain rate, and wire length on the buckling behaviour are investigated. The simulation results indicate that critical load clearly decreases with increasing tem...
متن کاملRefined Buckling Analysis of Rectangular Plates Under Uniaxial and Biaxial Compression
In the traditional buckling analysis of rectangular plates the classical thin plate theory is generally applied, so neglecting the plating shear deformation. It seems quite clear that this method is not totally appropriate for the analysis of thick plates, so that in the following the two variable refined plate theory proposed by Shimpi (2006), that permits to take into account the transverse s...
متن کاملBuckling Behavior of Composite Plates with a Pre-central Circular Delamination Defect under in-Plane Uniaxial Compression
Delamination is one of the most common failure modes in composite structures. In the case of in-plane compressional loading, delamination of a layered flat structure can cause a local buckling in delaminated area which subsequently affects the overall stiffness of the initial structure. This leads to an early failure of the overall structure. Moreover, with an increase in load, the delaminated ...
متن کاملBuckling Analysis of Rectangular Plates under the Combined Action of Shear and Uniaxial Stresses
In the classical buckling analysis of rectangular plates subjected to the concurrent action of shear and uniaxial forces, the Euler shear buckling stress is generally evaluated separately, so that no influence on the shear buckling coefficient, due to the in-plane tensile or compressive forces, is taken into account. In this paper the buckling problem of simply supported rectangular plates, und...
