Multilevel design optimization of composite structures with blended laminates

This research work deals with the design and optimization of a large composite structure. In design of large structural systems, it is customary to divide the problem into many smaller independent/semi-independent local design problems. The use of composite necessitates the inclusion of ply angles as design variables. These design variables are...

Local Cooling during Welding: Prediction and Control of Residual Stresses and Buckling Distortion

One of the major problems during welding of thin plate structures is the occurrence of buckling distortion. This type of distortion is caused by the formation of compressive welding stresses; when these stresses exceed a certain critical stress level, the structure will buckle. Most methods for eliminating the welding induced buckling distortion...

The Imperfection Data Bank and its Applications

Imperfections are irregularities of the shape of a thin-walled shell, such as those used for rocket structures or silos. Knowing the imperfections is very important as thin-walled shells are very sensitive to imperfections. Even a small deviation with respect to the perfect shell shape reduces the buckling load significantly. The main objective...

A Koiter-Newton arclength method for buckling-sensitive structures

Thin-walled structures, when properly designed, possess a high strength-to-weight and stiffness-to-weight ratio, and therefore are used as the primary components in some weight critical structural applications, such as aerospace and marine engineering. These structures are prone to be limited in their load carrying capability by buckling, while...

Optimum Design of Steered Fibre Composite Cylinders with Arbitrary Cross-sections

Automated fibre placement (AFP) machines are able to place simultaneously several bundles of fibres, called tows, on a surface. Using AFP machines, it is also possible to manufacture composite laminates with fibres placed in curvilinear paths. The fibre orientations and stiffness properties of these laminates are spatially varied and hence they...
