Multifield Variational Sectional Analysis for Accurate Stress Computation of Multilayered Composite Beams

Abstract: A multifield variational beam sectional analysis is proposed based on the Hellinger-Reissner principle for anisotropic beams with arbitrary cross-sectional geometries and material distributions. Both stresses and threedimensional (3D) warping deformations are treated as unknowns, which are modeled using the isoparametric finite element (FE) shape functions. The nodal stresses are solved on each material domain, resulting in the required continuity within the domain and discontinuity at the material interfaces.… Show more

“…Many beam theories have been devised for generic cross-section analysis methods with detailed cross-sectional warpings and elastic coupling effects of composites. These range from finite element (FE)-based cross-section analyses [5][6][7][8][9], polynomial or series expansion methods [10][11][12], closed-form elasticity solutions [13,14], contour-based analytic formulations [15][16][17][18][19], and to semi-analytic approaches [20][21][22].…”
