The method of mapping the damage parameters used in continuous damage mechanics (CDM) to the nodes and damping of the element stiffness matrix by the damage parameters are discussed. Since the method of constructing the global stiffness matrix from the element stiffness matrix in the element-free Galerkin method, one of the typical meshfree methods, is different from the finite element method, the continuous damage mechanical model as in the finite element method cannot be applied. To predict the damage initiation and crack propagation directions, the maximum principal stress criterion is used and CDM model is used to predict the damage evolution process under quasi-static loading. The calculated results are compared with several experimental results and show good agreement.</p> Hyo-Song Kim Jang-Chol Hwang Kumchol Yun Jun-Hyok Ri Chi-Myong Kim Copyright (c) 2026 European Journal of Computational Mechanics 2026-06-23 2026-06-23 449–470 449–470 10.13052/ejcm2642-2085.3461 https://journals.riverpublishers.com/index.php/EJCM/article/view/28083 <p>The present work examines free and forced vibrations of shape-memory alloy (SMA) annular sector plates. The first-order shear deformation theory is utilized to analyze the plate. The Boyd-Lagoudas constitutive model is used to simulate pseudoelastic behavior. Hamilton’s principle is employed to obtain motion equations. The sector plate time response and sector plate frequency response are derived via the return mapping algorithm, Newmark method, and differential quadrature method (DQM). In addition, the numerical results of the force vibrations and the effects of the different geometrical parameters on the dynamic response of the plate are investigated. Finally, the findings of this study are verified using the finite element method (ABAQUS software) and the findings of other studies.</p> Amir Hossein Nasrollah Barati Reza Shahveh Copyright (c) 2026 European Journal of Computational Mechanics 2026-06-23 2026-06-23 471–498 471–498 10.13052/ejcm2642-2085.3462
