... was determined using AE moment tensor inversion techniques. Orientation and direction of crack displacement vector and crack face normal vectors were calculated from an eigenvector decomposition of the moment tensor solution and provided valuable information regarding how individual microcracks contribute...

... to the treatment of any undergraduate textbook. Suppose we wish to describe the location of a plane in space, relative to some fixed cartesian coordinate system. The plane can be fully characterized by just two parameters: a normal vector and a point on the plane. The normal vector uniquely defines the orientation...
