This paper investigates the effect of different methods of carbon nanotubes distribution in a thin matrix on static and dynamic behavior of the nanocomposite. Five different symmetric patterns of distribution are considered, including four parabolic patterns and a linear one. For each pattern, the effective mechanical properties of the resultant nanocomposite are calculated using the rule of mi...
optimization of training results and improvement of response requires selecting appropriate stimulus and are goals of any training program. it seems that ischemic-reperfusion preconditioning (irpc) can be a suitable stimulus to increase submaximal contractile responses. therefore, this study aimed at investigating the effect of ischemic-reperfusion preconditioning and remote preconditioning (ir...
This research deals with free vibration and static bending of a simply supported functionally graded (FG) plate with the porosity effect. Material properties of the plate which are related to its change are position-dependent. Governing equations of the FG plate are obtained by using the Hamilton’s principle within first-order shear deformation plate theory. In solving the problem, the Navier s...

Abstract Layered composite materials are widely used across a variety of sectors, including the automotive industry, aerospace engineering, offshore, and various mechanical domains, because their strong yet lightweight structures. Therefore, emergent theories available on deformation layered beams. The previous research studies insufficient as they based sandwich arches with simply supported (S...
A finite element solution based on equevalent elements is proposed for the static and dynamic analysis of tallhigh tensioned cable antennas. To reduce high number of degrees of freedom in space frame body of a structure, a simple equivalent beam element is defined for each simulative substructure. This numerical procedure is applicable to analyze complex three dimensional assemblies of substruc...
Irregular buildings make up a large portion of urban infrastructure. Presence of irregularities can be due to architectural and user changes in building stories. Main objective of this article is evaluate seismic performance of structures with vertical irregularities. Seismic responses are obtained by enveloping peak inelastic responses resulting from pushover analyses according to provided p...
ANYONE with a stethoscope, a sphyg-momanometer, and an open mind can readily satisfy himself that static effort or "isometrics" may raise the blood pressure to high levels. Yet, isometrics, as a form of exercise intended as a means of attaining physical fitness, has been urged on the population at large. A recognition of the fact that the obese, the infirm, and the aged are unlikely to commence...
