Response of composite plates with random material properties using FEM and Monte Carlo simulation

Stochastic perturbation-based finite element for deflection statistics of soft core sandwich plate with random material properties

“…. ; b R ðx; yÞg (21) where the b i 's represent random parameters, i.e., Poisson's ratio, Young's modulus, mass density, etc. Using finite element approximation, the random field variables may be expressed in terms of nodal random variables similar to Eq.…”

“…Many researchers [18][19][20] considered the uncertainties in the material properties and analyzed their effect on the performance of composites. Naveenthraj et al [21] modeled the material properties as random variables and evaluated the static response characteristics of graphite/epoxy composite laminates for different boundary conditions, thickness ratio, aspect ratios and fiber orientations by using Monte Carlo simulation (MCS) and the finite element method (FEM). Salim et al [22] also considered the material properties (like elastic modulus, Poisson's ratio, etc.)…”

Free Vibration of Laminated Spherical Panels With Random Material Properties

“…Salim et al [20}22] have employed "rst order PT (FOPT) for analysis of composite plates using CLT with random material properties and have obtained the response statistics for static de#ections, natural frequencies and buckling loads of rectangular plates. The static response statistics of graphite}epoxy composite laminates with randomness in material properties to deterministic loading have been obtained by Navneethraj et al [23] using combination of "nite element method and MCS. Yadav and Verma [24] have investigated free vibration and initial buckling for circular cylindrical shells with random material properties using CLT and FOPT.…”

Stochastic nonlinear bending response of laminated composite plates with system randomness under lateral pressure and thermal loading

“…Based on higher-order theory, Naveenth Raj et al [10] evaluated the linear static response statistics of graphite-epoxy composite laminates with randomness in material properties for different boundary conditions, thickness ratios, aspect ratios and fiber orientations to deterministic loading by using combination of finite element analysis and Monte Carlo simulation (MCS). Salim et al [11] also examined the effect of randomness in material properties such as elastic modulus Poisson's ratios etc.…”
