Abstract: This paper proposes a method for projecting the propagation of a fillet-weld fracture. The model is based on photoelasticity testing of stress-strain state combined with destructive testing the fracturing resistance of fillet welds. The paper identifies the correlation of weld geometry and stress concentration/gradients. It shows that reconfiguring the flat body and/or reorienting the resultant external-load vector disrupts the symmetry in general, including the stress tensor field in the vicinity of the fracture apex. To project fracture propagation, this research uses differential geometry, in particular the properties of geodesic lines and gradient descent.
