Abstract The phase-field theory is a well-known mathematical model for solving interface problems, including crack problems in fracture mechanics. In this study, the formula is derived by variational approaches based on the Reissner-Mindlin plate kinematics and the multi-phase-field theory for simulation of the buckling phenomenon in cracked laminates. Phase-field parameters are defined independently in different plies of laminate to capture the crack behavior of each ply. Simulation is carried ...

ABSTRACTThis article focus on validation phase-field method for simulation of free vibration and buckling of crack plates. The formula is derived from using Reissner-Mindlin plate theory. Validation simulation is carried out by numerically investigating free vibration and buckling of cracked plate with taking the configuration, material property, crack location, and other relevant assumptions as the same with the comparing references. The article shows that phase-field approach can be used to es...

Abstract A finite element method and phase-field model used by authors have been firstly extended to the buckling analysis of stiffened functionally graded (FG) plate with cracks. The finite formulation of the plate is based on the first order shear deformation theory (FSDT). The material properties of the FG plate change from the bottom surface to the top one by a power-law function, the stiffener is full of the material, which is the same as the bottom surface, where the stiffeners are attache...

Triple-layered composite plates are created by joining three composite layers using shear connectors. These layers, which are assumed to be always in contact and able to move relatively to each other during deformation, could be the same or different in geometric dimensions and material. They are applied in various engineering fields such as ship-building, aircraft wing manufacturing, etc. However, there are only a few publications regarding the calculation of this kind of plate. This paper prop...

Abstract This study focuses on the investigation of the stability in a rectangular FGM plate with central crack. The plate thickness is changed linearly following the length of the plate. Using the Reissner-Mindlin first order shear deformation theory (FSDT), phase field theory and finite element method (FEM), the stability of fracture of the plate is determined. In order to ensure the reliability of the study, the obtained numerical results in this paper are compared with results reported in ot...

Abstract In this paper, the variational phase field model is adopted to analyze thermal buckling behavior of cracked functionally graded material (FGM) plates. Unlike existing works, the difference between neutral surface and mid-surface of FGM plates is taken into account in the present study. The kinematics of plate is based on first order shear deformation theory, while the crack is simulated by variational phase-field theory. The critical buckling temperature rises of cracked FGM plate is ca...

Abstract Modern structures and components may require advanced materials whose properties vary continuously not only in one specified direction, but also different other directions. In particular, the bi-directional functionally graded materials (2D-FGMs) introduced are expected to have more effective properties, consequently eliminating commonly awkward problems such as local stress concentrations and delamination. In this paper, buckling and bending behaviors of 2D-FGM plates, which are of gre...

Several models of variational phase field for fracture have been introduced and analyzed to different degrees of applications, and the rate-independent phase field approach has been shown to be a versatile one, but it is not able to accurately capture crack velocity and dissipated energy in dynamic crack propagation. In this paper, we introduce a novel rate-dependent regularized phase field approach to study dynamic fracture behaviors of polymethylmethacrylate materials, in which the rate coeffi...

In this paper, a model of statically stability plate with crack-based finite element analysis will be introduced by numerical simulation computation. The simulation model was built based on phase field theory in mechanics of fracture; the case study of plate was significantly computed with the new third-order shear deformation plate theory (TSDT), which is derived from an elasticity formulation, rather by the hypothesis of displacements [1]. Importantly, to verify of reliability of the modeling ...
