Active Aeroelastic Aircraft Structures,he wings and “aeroelastic weight penalty” became a widely used expression by engineers in aircraft design. Aeroelastic solutions generally involve increasing the structure stiffness or mass balance (passive solutions), which typically involve increase of weight and cost while decreasing performance.

Computational Methods for Dynamic Crack Propagation,onsidered include element deletion, interelement unzipping models and the extended finite element method. Element deletion consists of simply deleting the element when a material criterion is met. The inter-element crack models are of the type proposed by Xu and Needleman, and by Ortiz and Pandolfi.

Analysis and Design of Sandwich Structures Made of Steel and Lightweight Concrete,s inexpensive material has proven not to be commercially viable, primarily because of added weight. A new concept for design of ships and marine structures has been developed using sandwich plates composed of steel skins with lightweight concrete as core material. New types of light-weight concretes

,Strength of Porous Ceramics — Mechanical Testing and Numerical Modelling,has been occasioned by the industrial interest in the strength of ceramic filter supports used in nanofiltration, where internal pressure is of importance. Porous ceramics subjected to fluid pressure in the pores are prone to brittle microfracturing which may progress to brittle or quasi-brittle rup
