Ultrasonic wave propagation in thick, layered composites containing degraded interfaces
The ultrasonic wave propagation of thick, layered composites containing degraded bonds is investigated. A theoretical one-dimensional model of three attenuative viscoelastic layers containing two imperfect interfaces is introduced. Elastic material properties and measured 'values of ultrasonic …

Some simple explicit results for the elastic dielectric properties and stability of layered composites
… light on the behavior of dielectric elastomer composites — have been recently reported in the literature for the macroscopic electroelastic response and stability of layered composites with ideal elastic dielectric phases. Such results have been restricted to two phases and plane-strain loading …

The influence of alloy composition and interfacial segregants on the fracture and fatigue of metal/ceramic interfaces
The use of multi-layered composites in the aircraft, automotive, and electronics industries is becoming more common as performance requirements exceed the capabilities of homogeneous materials. As a result, the need to assess their failure is critical. Diffusion bonded joints, thermal-barrier and …

DEVELOPMENT AND IN-SITU CHARACTERIZATION OF BI-LAYERED LAMINATED COMPOSITES FOR ENHANCED MOISTURE BARRIER PERFORMANCE
… conditions. The diffusivity of both the bi-layered composites and the pure encapsulation materials was assessed using two distinct experimental methods for the calculation of diffusivity based on the principles of 1-dimensional Fick's law of diffusion. The diffusivities were statistically …

Implementation of Third Order Plate Theory for use in Existing Finite Element Software
Sandwich plates and layered composites are common in many structural applications because of their combination of high stiffness and low weight. These plates combine top and bottom layers of high Young's modulus with intermediate layers of material carrying predominantly shear loads. Finite …

On iso- and nonisothermal crack problems of a layered anisotropic elastic medium
The iso- and non-isothermal crack problems of layered fiber-reinforced composite materials are investigated within the framework of linear anisotropic thermoelasticity and under the state of generalized plane deformation. The crack is assumed to be parallel to the layer bounding surfaces. By …

Computational Modeling and Impact Analysis of Textile Composite Structutres
… has two: 1) studying behavior of textile composites under static loads, 2) studying dynamic responses of these textile composite structures subjected to the transient/ballistic loading. In the first part, efficient homogenization schemes are suggested to show the influence of textile …

Anti-plane Shear of Cylinders and Layered Systems: Cohesive Fracture and Instability
… and quasi-static growth in both cylinder and layered systems. The analysis, which is exact, is based on the solution of two fundamental elasticity problems: i) a cylinder subject to an arbitrary shear on one end cap and an equilibrating torque on the other and, ii) a layer subject to arbitrary …

Nonlinear vibration energy harvesting : fundamental limits, robustness issues, and practical approaches
… surface instability or in general instability in layered composites which is, in part, motivated by the BLSH strategy. Instabilities in soft matter and composite structures e.g. wrinkling allow large local strains to take place throughout the entire structure and at regular patterns. Unlike …
