A generalized multilength scale nonlinear composite plate theory with delamination

A generalized, multilength scale framework for thermo-diffusional-mechanically coupled, nonlinear, laminated plate theories with delaminations

“…Eq. (2.1) represents a generalization of the original displacement expansions used by Williams (1999) since it allows for different order expansions in the inplane and out of plane displacement components. The temperature field within the kth layer is assumed to be of the following form…”

“…The resulting governing equations are functions of the fundamental unknown kinematic, temperature, and solute variables used in the expansions for the different fields in the individual layers. The proposed theoretical framework is an generalization of the purely mechanical theory presented by Williams (1999).…”

A Coupled Approach to Developing Damage Prognosis Solutions

“…In order to correctly address the modeling issues associated with the composite material response, a novel multi-length scale finite element (MSFE) approach developed at LANL is being used [1]. The MSFE theory is based on a new generalized, nonlinear, multi-length scale plate theory shown schematically in Fig.…”

First-Order Displacement-Based Zigzag Theories for Composite Laminates and Sandwich Structures: A Review

“…In closing this introductory overview of the zigzag approaches for the analysis of laminated composite laminates and sandwich structures, it should be noted that they belong to the more general modern approaches, known either as Multi-scale or Global-local approaches [86,87,88,89,90,91,92], where the displacement field within each layeris represented as a superposition of a layer-wise field, defined over each layer, and a global field spanning the entire laminate. Thus, the governing equations exhibit explicit coupling between effects associated with different (global and local) length scales.…”
