Theoretical and Numerical Approximation Methods for Predicting Bending Characteristics of Bimodulus Sandwich Structures
Source abstract
Abstract
Sandwich materials are widely used in marine structures because of their excellent comprehensive properties. However, the solution of bimodulus is challenging. Therefore, the theoretical and numerical approximation methods for the analysis of load-bearing characteristics of bimodulus sandwich structures are put forward comprehensively in this paper. Based on the superposition principle, a theoretical method for calculating the neutral surface position of bimodulus sandwich plate is derived, and the corresponding bending control equation is obtained. The proposed theoretical approximation method can fully consider the sawtooth deformation between the plate and the core, as well as the sawtooth deformation inside the core at the tension–compression interface. Moreover, a finite element model is established for complex sandwich structures to analyze the influence of bimodulus. Numerical examples show that the theoretical approximation model proposed in this paper has higher calculation accuracy.
