Linear Models for Composite Thin-Walled Beams by Γ-Convergence. Part I: Open Cross Sections
We consider a beam whose cross-section is a tubular neighborhood, with thickness scaling with a parameter δε, of a simple curve γ whose length scales with ε. To model a thin-walled beam we assume that δε goes to zero faster than ε, and we measure the rate of convergence by a slenderness parameter s which is the ratio between ε2 and δε. In this Part I of the work we focus on the case where the c...
متن کاملLinear Models for Composite Thin-Walled Beams by Γ-Convergence. Part II: Closed Cross-Sections
We consider a beam whose cross-section is a tubular neighborhood of a simple closed curve γ. We assume that the wall thickness, i.e., the size of the neighborhood, scales with a parameter δε while the length of γ scales with ε. We characterize a thin-walled beam by assuming that δε goes to zero faster than ε. Starting from the three dimensional linear theory of elasticity, by letting ε go to ze...
متن کاملAn improved model for naturally curved and twisted composite beams with closed thin-walled sections
This paper presents an improved model for naturally curved and twisted anisotropic beams with closed thin-walled cross-sections. By introducing eigenwarping functions and expanding axial displacements in series of eigenwarpings, the differential equation involving the generalized warping coordinate and the expression for eigenvalues can be derived using the principle of minimum potential energy...
متن کاملModeling, vibration, and stability of elastically tailored composite thin-walled beams carrying a spinning tip rotor
The problems of the mathematical modeling, eigenvibration, and stability of cantilevered thin-walled beams carrying a spinning rotor at its tip are investigated. The structure modeled as a thin-walled beam encompasses nonclassical features such as anisotropy, transverse shear, and secondary warping, and in this context, a special ply-angle configuration inducing a structural coupling between fl...
متن کاملAxial Crush of Metallic and Hybrid Energy Absorbing Thin-walled Tubes with Polygonal Cross-sections: Numerical Analysis
Material properties and geometry are two important design parameters which their effects should be considered in a crashworthiness analysis. In this paper, the axial impact of metallic and hybrid energy absorbing thin-walled tubes with poly-gonal cross-section is simulated using LS-DYNA software. The combined effects of changing the geometry and material properties on the mass specific energ...
