Foam core sandwich composites are finding a wider breadth of use in aerospace, automotive, and construction applications. These structures present unique challenges in terms of material failure and interaction and are highly sensitive to damage and imperfections introduced during manufacturing. An emerging class of 3D Fiber Reinforced Foam Core (3DFRFC) aims to replace monolithic foams used in ...
Abstract A numerical analysis of the effect temperature on dynamics sandwich beam model with a viscoelastic core is presented. The under was described standard rheological model. This solution allows one to study material strength properties. Calculations were performed Finite Element Method in ANSYS software. results calculations showed significant influence properties test. confirmed damping ...
Sandwich plates with two thin stiff face-sheets and a soft center core have been used in many constructions for which the dominating load is transverse bending. Many theoretical/numerical analyses devoted to studying deformation mechanism of such structure. But relatively limited experimental investigations are present this field they often self-content little connection existing theoretical pu...
In this manuscript, by using the semigroup theory, well-posedness and exponential stability for a Rao-Nakra sandwich beam equation with internal damping time delay is proved. The system consists of two wave equations longitudinal displacements top bottom layers, one Euler-Bernoulli transversal displacement. To best our knowledge from literature , time, no attention was given to asymptotic model...
We report a new and highly versatile approach to artificial layered materials synthesis which borrows concepts of molecular beam epitaxy, self-assembly, and graphite intercalation compounds. It readily yields stacks of graphene (or other two-dimensional sheets) separated by virtually any kind of "guest" species. The new material can be "sandwich like", for which the guest species are relatively...
When curved and straight sandwich panels are joined, localized bending effects arise in the vicinity of the curvature discontinuity. To investigate this the problem is analyzed using a high order sandwich beam theory. This, however, is not straight forward because the continuity conditions at a junction cannot be fulfilled in an exact sense. Instead an averaging scheme is suggested and used to ...
