A general theory for anisotropic Kirchhoff–Love shells with in-plane bending of embedded fibers
نویسندگان
چکیده
This work presents a generalized Kirchhoff-Love shell theory that can explicitly capture fiber-induced anisotropy not only in stretching and out-of-plane bending, but also in-plane bending. setup is particularly suitable for heterogeneous fibrous materials such as textiles, biomaterials, composites pantographic structures. The presented direct extension of classical to incorporate the bending resistance fibers. It extends existing second-gradient initially straight fibers curved To describe additional kinematics multiple fiber families, so-called curvature tensor -- which symmetric second order proposed. effective stress moment tensors are then identified from mechanical power balance. These all general. Constitutive equations hyperelastic derived different expressions weak form it required computational formulations based on rotation-free finite element discretizations.

The mechanical behavior of cold rolled sheets is significantly related to residual stresses that arise from bending and unbending processes. Measurement of residual stresses is mostly limited to surface measurement techniques. Experimental determination of stress variation through thickness is difficult and time-consuming. This paper presents a closed form solution for residual stresses, in whi...

متن کاملAnalysis of Plane Waves in Anisotropic Magneto-Piezothermoelastic Diffusive Body with Fractional Order Derivative
In this paper the propagation of harmonic plane waves in a homogeneous anisotropic magneto-piezothermoelastic diffusive body with fractional order derivative is studied. The governing equations for a homogeneous transversely isotropic body in the context of the theory of thermoelasticity with diffusion given by Sherief et al. [1] are considered as a special case. It is found that three types of...
