### Shape factor image analysis and microscopy Wikipedia

Aspect ratio The most common shape factor is the aspect ratio a function of the largest diameter and the smallest diameter orthogonal to it The normalized aspect ratio varies from approaching zero for a very elongated particle such as a grain in a cold worked metal to near unity for an equiaxed grain The reciprocal of the right side of the above equation is also used such that the AR

Another example of the use of particle shape is in milling ablation and particle destruction It is often important to know the mechanism by which a particle is reduced in size For instance when milling a particle may fracture along large crystal faces forming two particles each with a lower aspect ratio Another possibility may be for small pieces to break off the particle eventually
