Comparison of a Higher Order Theory for Sandwich Beams with Finite Element and Elasticity Analyses

摘要: Sandwich construction is known to provide high stiffness with light weight. However the question of analysis methods for deformation and stresses in sandwich still not completely settled. A higher order theory beams has recently been presented literature. This compared a two-dimensional finite element elasticity solution present work. The results show that both predict strain concentrations faces adjacent support concentrated load regions, overall good agreement obtained between these methods. Classical first shear theories are capable predicting concentrations. Stress distributions core as due simplifying assumptions made by theory. an effective tool t...
