Carbon fiber-synthetic foam core sandwich composites are widely used for many structural applications due to their superior mechanical performance and low weight. Unfortunately these structures typically have very poor acoustic performance. There is increasingly growing demand in mitigating this noise issue in sandwich composite structures. This study shows that marrying carbon fiber composites...

MOTIVATION Giving a meaningful representation of a pedigree is not obvious when it includes consanguinity loops, individuals with multiple mates or several related families. RESULTS We show that finding a perfectly meaningful representation of a pedigree is equivalent to the interval graph sandwich problem and we propose an algorithm for drawing pedigrees.

Composite sandwich structural joints, such as T-joints, are used in many different composite applications to transfers the load orthogonally between two sandwich elements. However, these joints connecting the sections can represent the weakest link in sandwich composite structures due to the lack of reinforcement in the out-of-plane direction. Therefore, this paper presents a new methodology fo...

thermoplastic honeycombs based on polypropylene are one of the latest types of cores used in sandwich structures. up to now there have been few experimental and modelling studies on the mechanical behaviour of sandwich structures with thermoplastic cores. in this paper, by considering the similar properties of foams and thermoplastic honeycombs, attempts are made to model the static indentation...

In this paper, a new sandwich beam element is introduced for analyzing structures with flexible core and partially delaminated regions. element, interfaces between the face sheets are modeled by two independent layers. The model uses high-order panel theory to consider flexibility of nonlinearities associated geometry real contact characteristics proposed motion field takes advantage both displ...
