Abstract: A higher-order shear deformation theory is presented for vibration analysis of thick, doubly curved shallow shells. An orthogonal curvilinear coordinate system is employed to arrive at the strain ...

Abstract: This paper presents the formulation and numerical analysis for free vibration of a class of thick, shear deformable stress free shallow shells. Using the Ritz energy approach, the higher-order shell theory is presented ...

Abstract: This paper presents a free-vibration study of a new class of perforated plates with rounded corners. In contrast to the commonly used discretization methods, the vibration analysis is performed on a continuum-plate domain. ...

Abstract: A continuum approach based on the principle of minimum total energy is presented to study the free flexural vibration of doubly curved shallow shells of curvilinear planform. The Ritz procedure supplemented with the

Abstract: Many of the early works on symplectic elasticity were published in Chinese and as a result, the early works have been unavailable and unknown to researchers worldwide. It is the main objective ...

Abstract: Using the Eringen nonlocal theory (ENT), the integral constitutive relation (ICR) can be transformed into a corresponding differential constitutive relation (DCR). The inequivalence and equivalence between ICR and DCR have ...

Abstract: An analytical approximation is developed for solving large amplitude nonlinear free vibration of simply supported laminated cross-ply composite thin plates. Applying Kirchhoff’s hypothesis and the ...

Abstract: By introducing linear and constant terms with an undetermined parameter and subsequently using certain rules to determine the optimal value of the parameter, we establish analytical approximate ...

Abstract: This paper presents analytical approximate solutions for the geometrically nonlinear, large deformation postbuckling of a linear-elastic and hygrothermal beam with axially nonmovable pinned-pinned ends and subjected to a ...

Abstract: This paper investigates the free vibration of thick plates with rounded corners subject to different boundary conditions. The periphery of this class of plates is defined by a superelliptical function, and the degree of ...
