Cross product of a tensor and a vector

WebGiven two linearly independent vectors a and b, the cross product, a × b (read "a cross b"), is a vector that is perpendicular to both a and b, [1] and thus normal to the plane containing them. It has many applications in mathematics, physics, engineering, and computer programming. Webwhere F is the force vector, b is the Burgers vector, σ ij is the stress tensor, and n j is the j-th component of the unit vector normal to the slip plane. Given that the dislocation line direction is t̂ = ẑ and the Burgers vector is B→ = bsinθ𝑥̂ + bcosθ𝑧̂, we can write the unit vector normal to the slip plane as:
