A solution is given for a partially bridged straight crack in orthotropic elastic material in particular unidirectionally fiber-reinforced brittle composite. The problem of crack with constant bridging forces is solved by use the complex potentials. By use of Novogilov’s fracture criterion the estimation of the bridged part of crack and full length of equilibrium crack is obtained.
