Static and buckling analyses of stiffened plate/shell structures using the quadrilateral element SQ4C

Evaluation of Piezoelectric-based Composite for Actuator Application via FEM with Thermal Analogy

“…In terms of computational methods, Finite Element Method (FEM) has been an established approach for structural analysis, including for composite structures. Shell and plate theories have been well developed for FEM with continuous improvement [29][30][31]. One of the earliest developments of piezoelectric structure using FEM was discussed by Tzou and Tseng [32].…”

“…Thus, a piezoelectric model via 3D elements will exhibit some shortfalls, i.e., very dense meshing configuration and over-stiffness in bending [40]. Moreover, the model with very thin elements requires special treatment to avoid issues such as shear and membrane locking [29]. From the previous studies, some alternative techniques have been proposed to model piezoelectric structures in commercial software, i.e., equivalent circuits, spring models, and thermal analogy approach [39,41].…”

Effect of porosity on free vibration of functionally graded porous beam based on simple beam theory

“…If it is for thermal, or corrosive resistance or malleability and toughness, both strengths of the material may be used to avoid troubles related to above issues [1][2][3]. Due to the wide application of smart materials, various studies have been conducted on the mechanical behavior of structures as [4][5][6][7][8][9][10][11]. However, this material can exhibit some deficiencies such as porosity during the manufacturing process [12][13].…”
