Cylindrical basis vectors

Note: This page uses common physics notation for spherical coordinates, in which is the angle between the z axis and the radius vector connecting the origin to the point in question, while is the angle between the projection of the radius vector onto the x-y plane and the x axis. Several other definitions are in use, and so care must be taken in comparing different sources. WebIn the current configuration Abaqus formulates the equations in terms of a fixed spatial basis with respect to the axisymmetric twist degree of freedom. The basis vectors convect with the material. However, because of the axisymmetry of the model in the deformed configuration, these vectors can be defined at Θ = 0 as

Basis Vectors We are very familiar with the basis vectors of the Cartesian coordinate system; these are the unit vectors that define the system, and are simply the familiar x `, y `

WebWell, these are coordinates with respect to a basis. These are actually coordinates with respect to the standard basis. If you imagine, let's see, the standard basis in R2 looks like this. We could have e1, which is 1, 0, and we have e2, which is 0, 1. This is just the convention for the standard basis in R2. WebBasis Vectors We can achieve a more compact representation of ~rby introducing basis vectors associated with the cylindrical coordinates. The key observation is that the basis vectors are tangential to the lines of the coordinate mesh, which suggests a relationship between the basis vectors and derivatives of ~rwith respect to ˆ;˚;z.
