Asymmetrical Creep Bqckling of Clamped Shallow Spherical Shells

Optimization of Cylindrical Shells Under Combined Loading Against Brittle Creep Rupture

Optimal structural design of cylindrical shells under overall bending, torsion, tension and internal pressure in creep conditions is considered. The material is assumed to be governed by the Norton-Odqvist nonlinear steady creep law. Minimal weight of the shell is the design objective, radius and wall thickness are design variables, and the constraint refers to brittle creep rupture as describe...

Analysis of multi-layered microelectronic packaging under uniformly distributed loading

An accurate estimate of interfacial stresses in multi-layered microelectronic packaging is very important for design and prediction of delamination-related failures. An analytical model for stress analysis of multi-layered stacks, which is based on an extension of Valisetty s model (Bending of Beams, Plates and Laminates: Refined Theories and Comparative Studies, Ph.D. thesis, Georgia Institute...

Bifurcation Buckling of Shells of Revolution including Large Deflections, Plasticity and Creep

A summary is first presented of the conceptual difficulties and paradoxes surrounding plastic bifurcation buckling analysis. Briefly discussed are nonconservativeness, loading rate during buckling, and the discrepancy of buckling predictions with use of .I2 flow theory vs JZ deformation theory. The axisymmetric prebuckling analysis, including large deflections, elastic-plastic material behavior...
