A finite element model to study the buckling behaviour of general orthotropic, midplane symmetric and elastic plates

A finite element model has been developed, which incorporates the bending-torsional coupling effect, as it occurs in general orthotropic, midplane symmetric, elastic plates in order to analyse its influence on the buckling behaviour of such plates. Some results have been compared with known exact and approximate solutions.

Simulation of thermal cycle aging process on fiber-reinforced polymers by extended finite element method

The simulation of long life behavior and environmental aging effects on composite materials are subjects of investigation for future aerospace applications (i.e. supersonic commercial aircrafts). Temperature variation in addition to matrix oxidation involves material degradation and loss of mechanical properties. Crack initiation and growth...
