Tunability of Mechanical Behaviors in Multi-Morphology Functionally Graded Porous Beams with TPMS Architectures

Size-dependent bending, buckling, and vibration behavior of a nanobeam with periodically distributed holes via a PINN-based method

Numerical investigation on the static and modal characterization of functionally graded Triply Periodic Minimal Surface (FG-TPMS) structures: From homogenization to explicit modelling

This study presents a finite element framework to analyse the static bending, stress-strain fields, and dynamic eigenfrequencies of functionally graded Triply Periodic Minimal Surface (FG-TPMS) beam structures. Effective material properties of a Gyroid unit cell are extracted via micromechanical homogenization and assi...

Nonlinear dynamic modeling and analysis of functionally graded porous circular/annular plate supported by nonlinear elastic foundation

Nonlinear large-deflection dynamic buckling pressure of helically stiffened FG-GRC toroidal shell segments with porous core

This paper presents an analytical investigation of the nonlinear dynamic buckling behavior of hollow-core functionally graded graphene-reinforced composite (FG-GRC) circular toroidal shell segments subjected to rapidly increasing external pressure. The shell structure is composed of FG-GRC face sheets and a porous core...

Effects of lattice stiffeners on the nonlinear behavior of variable-curvature FG-GRC panels subjected to blast and step loads

This paper presents a semi-analytical investigation of the nonlinear dynamic responses of lattice-stiffened variable-curvature functionally graded graphene-reinforced composite (FG-GRC) sandwich panels with a porous core under impulsive loading conditions. The structure consists of FG-GRC face sheets and a lightweight...

Vibration characteristics of bidirectional functionally graded curved structures with cracks and variable porosity

The free vibration analysis of a bidirectional functionally graded (2D-FG) curved structure with a through-thickness longitudinal central crack is performed in the current analysis. The model employs higher-order displacement theory for kinematics, taking into consideration both situations with even and uneven porosi...
