To use in jupyter notebooks use function vedo.embedWindow(), you may want to install k3d with: To install it use: pip install vtk=8.1.2 (if available on your system). Sometimes an older version of VTK can yield better visualizations with transparent objects, To install the latest dev version of vedo: This study provides a promising method to reveal and quantify the hidden stresses that govern the non-planar propagation of a 3D fracture in solids.Pip install vedo additional installation details ![]() The variation of stress value along the depth direction indicates the deflection of the crack surface as the fracture approaches the free surface of the specimen. The results indicate that the 3D stress distribution undergoes obvious fluctuations along the depth direction of the penetrated crack. In this study, we report an experimental method to quantify the evolution of the 3D full-field stress along the depth of a penetrated crack via 3D printing technology, frozen-stress techniques, photoelastic testing, and phase-shifting methods. This is because the fracture propagation trajectory is a spatial, non-planar surface whose stress field is too complex to be accurately characterized by the existing theories. It is challenging for traditional fracture mechanics theories to directly reveal and accurately quantify the hidden stress field associated with 3D crack initiation and propagation. ![]() The initiation and propagation of a pre-existing three-dimensional (3D) fracture depends on the magnitude, distribution, and evolution of the full-field stress in the vicinity of the fracture. ![]()
