Creep Damage and Fracture

1982
The creep data obtained during C0ST50, round II, have been reanalyzed according to the recovery creep model modified for precipitation strengthening mechanisms. A good description of creep data is obtained in this way for all cases studied. A dislocation climb bypassing mechanism is indicated as beeing the governing process in service applications of ...

Coupled thermo-damage and damage-fracture fields

1999
The creep process and the associated material deterioration are temperature sensitive phenomena. A classical approach consists in accounting for the effect of temperature on the material functions in the constitutive and the evolution equations of a damaged solid (cf. Ganczarski and Skrzypek, 1991), whereas the temperature field remains steady state.

Sacrum fractures and neurological damage

Journal of Neurosurgery, 1977
✓ Two cases are presented in which automobile collision caused transverse sacral fracture involving neurological elements. The patients were admitted within 2 weeks of each other to the Maryland Institute for Emergency Medicine. An attempt was made to assess the incidence of this condition and its relation to fractured pelvis.
