Christoffel符号的意义

WebConnection coefficients, also called Christoffel symbols, are coordinate-dependent coefficients that are needed to specify the Levi-Civita connection. The connection coefficients therefore define a notion of differentiation on an arbitrary Riemannian manifold. Let’s try to understand this in a bit more detail. WebThe Christoffel equation for a ply is set up as follows: Substitute Eq. (9.4) into Eq. (9.2) and use ω=ξv to write. Recall the ply stiffness matrix for an off-axis monoclinic ply, that is, Recall the equation of motion in terms of displacements, that is, where cijlm, i, j, l, m =1,2,3 is the stiffness tensor.

WebMar 5, 2024 · In other words, there is no sensible way to assign a nonzero covariant derivative to the metric itself, so we must have ∇ X G = 0. The required correction therefore consists of replacing d / d X with. (9.4.1) ∇ X = d d X − G − 1 d G d X. Applying this to G gives zero. G is a second-rank tensor with two lower indices. http://staff.civil.uq.edu.au/h.chanson/civ4160/70_conf.pdf
