The Halpin-Tsai equations are based upon the “selfconsistent micromechanics method” developed by Hill. Hermans eniplovetf this model to obtain a solution in terms of Hill’s “reduced moduli”. Halpin and ’Tsai have reduced Hernians’ solution to a simpler analytical form arid extended its use for a variety of filament geometries. The development of these niicromechanics relationships, which form t...

the free vibration of the lattice cylindrical composite shell reinforced with carbon nano-tubes (cnts) was studied in this study. the theoretical formulations are based on the first-order shear deformation theory (fsdt) and then by enforcing the galerkin method, natural frequencies are obtained. in order to estimate the material properties of the reinforced polymer with nano-tubes, the modified...

in this research, the influence of adding micro- and nano- sized calcium carbonate powders to nylon-66 was investigated. mechanical properties of micro and nano- composites, including tensile strength, elongation, and young’s modulus, before and after ageing, were determined and analyzed. for this purpose, micro- and nano-sized caco3 particles were used as fillers to prepare micro-composites (c...

̄ Although a number of testing methods (Myers 1979) (Suwa, Scott, & Shortliffe 1982) (Nguyen et 1987) (Ould & Unwin 1987) (Tsai & Zualkernan 1990) (Gupta 1991) (Tsai, Zualkernan, & Kirani 1992a) have been proposed for testing expert systems, recent studies (Zualkernan, Tsai, & Kirani 1992) (Tsai, Sirani, & Zualkernan 1992b) (Tsai, rani, & Zualkernan 1993) suggest that conventional testing method...
