A study on buckling of thin conical frusta under axial loads

Eigenvalue Buckling Computation and Impact on Pipeline Wall Thickness and Subsea Depth

“…The specimens were subjected to axial compression between two rigid plates and the load-deflection relationship showed linearity. The experimental result was found to be analogous to the numerical result and concluded finite element method was a more cost and time effective way to determining buckling load [12].…”

Bending collapse of thin-walled circular tubes and computational application

“…Model 1 has the same geometry as the previous simplified model except that it is made of aluminum instead of the mild steel. For aluminum with density 2700 kg/m 3 , its Young's modulus is 70 GPa, its Poisson's ratio is 0.33, its yield stress value is 55 MPa, and a tangent modulus 4 GPa has been taken [17]. Model 2 is also made of aluminum and its cross-section has radius R ¼ 30 mm and the wall thickness t ¼ 1.5 mm.…”

Effect of heat treatment on the blast loading response of combined geometry shell core sandwich structures

“…The global deformation of the shell was progressive and the deformation mode of conical frusta part was found to be different from that of the geometry without a cap [2]. Niknejad and Tavassolimanesh [3] investigated the inversion process of an end-capped frusta.…”
