Bistable carbon fiber composites, whose bistability arises from having asymmetric layouts in different layers, have shown immense potential for using shape morphing and adaptive structure applications. While many studies this field focus on these composite laminates' external shapes at the two stable states, their snap-through behavior of shifting one to other remains a critical aspect be inves...

astrophysics is becoming now an integral part of general physics. considering the black hole theory ,which is a new and exciting branch of relativistic astrophysics, we see many connections between elementary particle physics and astrophysics. in this article we attempt to explain the development of star physics ,in an easy ,understandable manner. previous knowledge of relativistic theory or cl...

deflection analysis of a simply supported microbeam subjected to a concentrated load at the middle is investigated on the basis of a shear deformable beam theory and non-classical theory. effects of shear deformation and small size are taken into consideration by hyperbolic shear deformable beam theory and modified strain gradient theory, respectively. the governing differential equations and c...

Abstract Carbon fiber reinforced plastic (CFRP) laminates are often used in a quasi-isotropic manner, such as cross-ply lamination; thus, the mechanical properties of CFRP cannot be fully exploited. In this study, we proposed carbon design method, which uses orientation and thickness lamination parameters, where is determined using principal stress direction by iterative calculations maximum th...
