Brief Notes: Logarithmic Screw Dislocation

Z. Wesołowski
Technical University of Kielce

Basing on linear elasticity, the displacement field $u_z =B\vartheta \ln r$ (in cylindrical coordinates $r, \vartheta, z$) was derived. This displacement has a jump on the half-plane $\vartheta = 0$. Stresses orthogonal to this discontinuity plane are continuous.
