Buckling analyses of heavily corrugated cylindrical shells based on detailed full finite element models are usually computationally expensive. To address this issue, we have proposed an efficient computational method of predicting the onset of buckling for corrugated cylindrical shells which builds on the Bloch wave method for infinitely periodic structures. We modified the traditional Bloch wa...

Nowadays, composite materials are increasingly used in the most diverse areas of engineering, where non-planar geometries begin to be quite frequent. However, existing knowledge about its mechanical performance is still not enough for structural applications. Therefore, experimental tests were carried out study thickness effect on static compression and multi-impact response laminated E-glass/P...

In recent years, wood fibres have often been applied as the reinforcement of thermoplastic materials, such as polypropylene, whereas their use in combination with thermosetting resin has been less widespread. This study concerns the production of PMMA-based composites by partly replacing alumina trihydrate (ATH) with wood waste fillers, namely rice husks and almond shells, which would otherwise...

219-235, ASME winter meeting, Anaheim, CA, Nov. 1998. ABSTRACT A new finite element approach to sandwich shells is proposed. It uses existing shell finite elements formulated for homogeneous shells. The “sandwich” nature of the problem is hidden from the main finite element program. Based on several assumptions the proposed homogenization procedure calculates stress increments in a homogeneous ...
