Plane strain tension fracture at high strain rate [PDF]
EPJ Web of Conferences, 2021 Under plane stress conditions, most micromechanical and phenomenological models predict a minimum in ductility for plane strain tension stress state.

Criteria of Ductile Fracture Strain
Bulletin of JSME, 1972 Two criteria of ductile fracture strain are suggested. From the theory of plasticity for porous materials, the following criterion of fracture for a triaxial state of stress is obtained: [numerical formula] where ee_qf is the equivalent fracture strain, σm the mean stress, σe_q the equivalent stress, a0 and b0 are constants.

A New Model for Void Coalescence by Internal Necking [PDF]
, 2010 A micromechanical model for predicting the strain increment required to bring a damaged material element from the onset of void coalescence up to final fracture is developed based on simple kinematics arguments.

Machine Learning for Predicting Fracture Strain in Sheet Metal Forming
Metals, 2022 Machine learning models are built to predict the strain values for which edge cracking occurs in hole expansion tests. The samples from this test play the role of sheet metal components to be manufactured, in which edge cracking often occurs associated ...

Fracture healing monitored with strain gauges [PDF]
Acta Orthopaedica Scandinavica, 1992 We measured healing in 7 cases of surgical neck fracture of the humerus by applying a strain gauge measuring bar between the external fixation pins. Repeated measurements provided a healing curve for the individual cases. The gradual decrease in deflection of the fracture zone reached a plateau of about 50 percent after 2 to 4 weeks in 6 cases.

Evaluation of impact ductile fracture behaviour of low carbon austenitic stainless steel SUS304L using damage mechanics model [PDF]
EPJ Web of Conferences, 2021 To clarify the applicability of the Gurson-Tvergaard-Needleman (GTN) model for impact ductile fracture behaviour, SHB test was reproduced by finite element analysis (FEA).
