Herein, we apply the TDC for the reformulation of the classical Kirchhoff–Love shell theory which is typically formulated based on a given parametrization. Based on the TDC, it is possible to also formulate the boundary value problem (BVP) for shell geometries where no parametrization is given ...
Abstract A thin shell formulation is developed for the approximation by a meshfree Reproducing Kernel Particle Method (RKPM). The formulation is derived from a degenerated shell approach where the structure is treated as a 3D solid subjected to kinematic constraints of the Kirchhoff–Love (KL) shel...

The Kirchhoff-Love shell theory is recasted in the frame of the tangential differential calculus where differential operators on surfaces are formulated without the need for a parametrization, i.e., local coordinates. The governing equations are presented in strong and weak form including a detailed...
2Isogeometric Kirchhoff–Love shell analysis In this section, we provide a brief background on the Kirchhoff–Love shell formulation. For more details on this formulation, we refer to [3,4,5,57,58]. Check punctuation!! 2.1Shell kinematics ...
Kirchhoff-Love假设 Kirchhoff-Love假设，物理学术语。1、垂直于中面方向的正应变，即εz，可以不计。2、应力分量τzx、τzy、σz远小于其余三个应力分量，因而是次要的，它们所引起的形变可以不计。3、薄板中面内的各点都没有平行于中面的位移，即 （u）z=0=0， （v）z=0=0。
