1polar coordinates A coordinate system in which apoint in the plane is located in terms of its distance r fromthe origin and the angle 0 between the positive x-axis andthe line connecting the point to the origin,measuredcounterclockwise in radians.The polar coordinates of apoint with rectangular...
(redirected fromPolar plane) polar coordinate system A system of coordinates in which the location of a point is determined by its distance from a fixed point at the center of the coordinate space (called the pole), and by the measurement of the angle formed by a fixed line (the polar ax...

Another numerical method is provided for plane elasticity in polar coordinate. Elasticity problems are always solved with one kind of variables in Lagrange system. Traditional FDM includes stress difference method and displacement difference method. These difference methods have some particular limit because...

(not to be confused with apole of a functionincomplex analysis, which is anisolated singularity). Every point is defined in terms of anangleand aray(a line that starts at given coordinates and extends to infinity) from the pole. The pole on a polar coordinate system is (0,φ), where...
[84]. If the studied plates are tested with a quadratic aperture, a Cartesian coordinates system is needed. A polar coordinate system is defined for a circular aperture[85]while the use of cylindrical coordinates is recommended for curved plates[85–88]. In the latter case, convex plates or...
