چکیده

The property profile exhibited by cellular metals identifies several applications, especially in technologies requiring multifunctionality. Their specific property attributes suggest implementation as: ultralight panels/shells, energy absorbing structures and heat dissipation media as well as for vibration control. Connections between the properties that govern these performance benefits and the cellular architecture, cell morphology and density have been made. Such structural relations facilitate choices of optimum cell characteristics for defined multifunctional applications.

This paper discusses a summary of analytical modeling as applied to selected smart composites which include piezoelectric composites, shape memory alloy (SMA) fiber composites, and piezoresistive composites. First we discuss the definition of ‘smart materials’ which exhibit coupling among mechanical, thermal and electromagnetic behavior, then the Eshelby’s formulations based on a simple algebra...

This paper presents a finite element formulation of elasticity to model elastic fracture in composites with long aligned fibers. We have employed a B-bar type approach which is applicable to compressible as well as nearly incompressible material systems. An energy approach is undertaken to evaluate the stress intensity factor at the crack tip. The effects of strong intact bridging fibers, fiber...

A methodology is introduced to test carbon-fiber-reinforced, hoop-wound composite cylinders for their biaxial mechanical properties under axial compression and hoop tension. The understanding of the behavior of these composites under biaxial loads is extremely important in the design of pulsed magnets. These composites are used as reinforcements for both the inner conducting layers and as an ov...

Debonding of films attached to substrates as well as fibers embedded in matrices typically involves initiation, steady-state propagation and a final transient as the debond converges on an edge or another debond. The emphasis in this paper is on the mechanics of the transient. Under most circumstances, a converging debond crack is characterized by an energy release rate that approaches zero, ca...

By appropriate annealing of rapidly quenched NddFe13.1B (2.05,d,147.6) the amount and microstructure of the Nd2Fe14B grains in the Nd-rich matrix were systematically controlled and correlated with coercivity, m0Hc. For optimally annealed NddFe13.1B an increase in Nd concentration enhances m0Hc of the Nd2Fe14B grains (from 1.2 T in Nd2.05Fe13.1B to 2.75 T in Nd147.6Fe13.1B at 290 K) and promotes...
