Fracture Toughness and R-Curve Behavior of Laminated Brittle-Matrix Composites
The fracture toughness and resistance-curve behavior of relatively coarse-scale, niobium/niobium aluminide (Nb/Nb3Al) laminated composites have been examined and compared to other Nb/Nb3Al composites with (in situ) Nb particulate or microlaminate reinforcements. The addition of high aspectratio Nb reinforcements, in the form of 20 vol. pct of 50to 250-mm-thick layers, was seen to improve the to...

15 صفحه اولElectromagnetic Shielding Effectiveness Evaluation For Materials
The theory of electromagnetic shielding is based on the waves equations describing the behavior of electromagnetic field in material. The proposed approach consist in a PSpice model using transmission line model to simulate the attenuation introduced by a material characterized by the macroscopic parameters ε, μ, σ. To verify the data obtained through PSpice simulation, a wave-guide-based measu...
متن کاملReliability Based Design of Multilayered Composites for Electromagnetic Shielding Applications
This paper presents a reliability based design study of multilayered composites for electromagnetic interference shielding applications. In this study, uncertainties in the design and external variables affecting the shielding effectiveness (SE) are modeled based on probability distributions. Monte Carlo simulation is employed at each design point generated via Latin hypercube sampling approach...
متن کاملFatigue-Crack Propagation Behavior of Ductile/Brittle Laminated Composites
A study has been made of the fatigue-crack propagation properties of a series of laminated Nbreinforced Nb3Al intermetallic-matrix composites with varying microstructural scale but nominally identical reinforcement volume fraction (20 pct Nb). It was found that resistance to fatigue-crack growth improved with increasing metallic layer thickness (in the range 50 to 250 mm) both in the crack-divi...
