scheurtype
Scheurtype is a Dutch-language term used to describe a classification of cracks in materials and structures. It refers to the characteristic pattern, origin, and propagation path of a crack, and is used in engineering, geology, and materials science to assess damage, predict growth, and decide on repairs. In fracture mechanics, crack behavior is often described in terms of modes: opening (mode I), in-plane sliding (mode II), and out-of-plane tearing (mode III). The concept of scheurtype is used to summarize which of these modes predominates in a given crack, or to describe observable features of the crack surface.
Common scheurtypes include tensile cracks that open under normal stresses, shear cracks that propagate along shear
Determination of scheurtype relies on visual inspection and, where appropriate, non-destructive testing methods such as ultrasound,
Importance: identifying the scheurtype supports risk assessment, informs repair strategies, and aids in lifetime prediction for
