= Mixed dislocation
A <mixed dislocation> has a line direction neither parallel nor perpendicular to its <Burgers vector>, combining screw and edge character. Along a curved dislocation line, the local character can change continuously while the Burgers vector remains fixed.
A dislocation loop therefore need not be assigned one character everywhere. Decomposing a local segment into edge and screw contributions helps analyze its stress field, mobility, and interaction with obstacles.
