A mixed variational framework for higher-order unified gradient elasticity

S. Ali Faghidian et al.

Summary: The proposed higher-order unified gradient elasticity theory effectively characterizes the nanoscopic response of advanced nano-materials, as demonstrated by its application to study the torsional behavior of elastic nano-bars and determine the shear modulus of nano-sized bars in closed-form analytical formula. Additionally, a practical approach to calibrate characteristic lengths is introduced.

Nonlinear thermo-mechanical static analysis of toroidal shells made of nanocomposite/fiber reinforced composite plies surrounded by elastic medium

Mohammad Amin Shahmohammadi et al.

Summary: This article evaluates the geometrical nonlinear behavior of toroidal shell segments under axial edge-loading and external pressure surrounded by an elastic medium, taking into account thermal effects. The article proposes an analytical solution using the Galerkin method based on the first-order shear deformation theory. The proposed method provides a robust tool for the geometrical nonlinear static analysis of hybrid composite shells with no computational efforts and is simpler than previous formulations. Verification procedures and parametric studies demonstrate the effectiveness of the proposed method for nonlinear analysis of such shells.

Vibration analysis of scale-dependent thin shallow microshells with arbitrary planform and boundary conditions

Amir Mehdi Dehrouyeh-Semnani et al.

Summary: This article provides a thorough investigation into the natural frequencies and mode shapes of thin doubly curved shallow microshells by considering the influence of material length scale parameter. The mathematical model is obtained using Hamilton's principle, modified couple stress theory, and Kirchhoff-Love's shell theory, with the free vibration characteristics extracted using the finite element method. The study includes comparative studies to verify the quadrilateral thin shallow shell element and presents numerical results for various types of shallow microshells with different planforms.

On the simulation of image-based cellular materials in a meshless style

S. M. Mirfatah et al.

Summary: A meshfree method is proposed for simulating Poisson's equation on 3D image-based cellular materials using fixed grids. Non-boundary fitted discretization of complex geometries is achieved by embedding micro-CT scan images in a Cartesian grid. The method utilizes modified singular functions and library-rational-exponential basis functions to construct an enriched spatial solution on a generic computational cloud of nodes.

Contribution of nonlocal integral elasticity to modified strain gradient theory

S. Ali Faghidian

Summary: The nonlocal integral elasticity and the modified strain gradient theory are integrated in the framework of the nonlocal modified gradient theory of elasticity, capturing size-dependent effects in nano-beams. The proposed nonlocal modified gradient problem is well-posed, demonstrated through analytical examination and comparison with molecular dynamics simulation. The stiffening effect of the gradient characteristic parameters is confirmed, providing an effective approach for nanoscopic study of field quantities.
