Sejhedstærskel
Sejhedstærskel is a Danish term used in materials science and biomechanics to denote the toughness threshold of a material or tissue—the minimum energy, stress, or deformation required to initiate significant damage or crack growth under a given loading condition. The word combines sejhed (toughness or resistance) with tærskel (threshold), reflecting its role as a boundary between safe and damaging loading.
In practice, sejhedstærskel can be defined in several related ways depending on the context. Energy-based thresholds
Measurement of the sejhedstærskel relies on standardized testing or controlled experiments. Methods include fracture toughness tests
Applications of sejhedstærskel include material selection and safety design, where designers use the threshold to establish
