Abstract Hybrid adhesive joints of metal and composite parts are increasingly common features lightweight structures. Efficient design these requires computational methods for estimating the fatigue life as well being joined – i. e. adherends. The paper focuses on prediction carbon fiber reinforced polymer (CFRP) adherends in hybrid joints. After a brief description material considered, two mod...

In this presentation, the structural performance of fiber reinforced composite laminate Pi joints is studied through a progressive failure analysis (PFA) method. The bonded joint area that is the weakest link of the Pi joint structure is modeled using the discrete cohesive zone method (DCZM). The damage growth and failure of the bonded interface is modeled through an exponential decaying tracti...

Lamb waves occur in thin-walled structures two wave modes—the symmetric and the antisymmetric mode. Their oscillation on structures‘ surfaces is either phase (symmetric) or shifted by a angle of ? (antisymmetric). In this work, method developed which to compare surfaces’ relation answer question whether fiber metal laminates show same surface behavior as described for metals. The evaluation tim...

This paper presents a 1 m long self-deployable boom that could be folded around a spacecraft. Previously developed simulation techniques are used to analyze this two-hinge boom, made from two-ply plain weave carbon fiber laminate. A stress-resultant based failure criterion is used to study safety of the structure during both stowage and dynamic deployment. A safe design that latches without any...

An innovative approach to glass fiber reinforcement in laminates promises to resolve existing challenges with mechanical, electrical, and performance characteristics typically encountered in today’s high tech printed circuit designs. This uniquely woven glass fabric is flatter and thinner, which results in a more uniform laminate for mechanical and laser drilling. Furthermore, special propertie...

background: this in vitro study investigated the marginal fit of two porcelain laminate veneers to help the selection of more accurate veneers in discolored teeth. materials and methods: thirty impressions of metal master die created from the prepared labial surface of an acrylic maxillary central incisor were made and poured with type iv stone. the dies were distributed into test groups (n = 1...

Fiber metal laminate (FML) is a kind of lightweight material that has garnered much attention in recent years due to its excellent properties under tensile, flexure, and impact conditions. However, little been paid the evolution aluminum alloy during FML forming process. In this paper, effects specimen thickness non-isothermal process on creep behavior AA2024 alloy, which generally used FMLs, w...

In this paper Knowledge Discovery System (KDS) is proposed and implemented for the extraction of knowledge-mean stiffness of a polymer composite material in which when fibers are placed at different orientations. Cosine amplitude method is implemented for retrieving compatible polymer matrix and reinforcement fiber, which is coming under predicted fiber class, from the polymer and reinforcement...
