---|---|---|
Normal component | Tangential component | |
Right Boundary \(\theta = \theta _{i}\) | \(u_{r}(r,\theta _{i}) = 0\) | \(u_{\theta } (r,\theta _{i}) = 0\) |
Left Boundary \(\theta = \theta _{\max } = \theta _{i} + \theta _{e}\) | \(u_{r}(r,\theta _{\max } ) = 0\) | \(u_{\theta } (r,\theta _{\max } ) = 0\) |
Inner Boundary \(r = r_{\mathrm{ib}}\) | \(\sigma _{r}(r_{\mathrm{ib}},\theta ) = 0\) | \(\tau _{r\theta } (r_{\mathrm{ib}},\theta ) = 0\) |
Out Boundary \(r = r_{\mathrm{ob}}\), θ ≤ 90∘ | \(\sigma _{r}(r_{\mathrm{ob}},\theta ) = - q(\lambda \cos \theta + \sin \theta )\) | \(\tau _{r\theta } (r_{\mathrm{ob}},\theta ) = - q(\cos \theta - \lambda \sin \theta )\) |
Out Boundary \(r = r_{\mathrm{ob}}\), θ>90∘ | \(\sigma _{r}(r_{\mathrm{ob}},\theta ) = - q( - \lambda \cos \theta + \sin \theta )\) | \(\tau _{r\theta } (r_{\mathrm{ob}},\theta ) = - q(\cos \theta + \lambda \sin \theta )\) |
