Therefore, the emphasis in this paper is on time-dependent fracture mechanics (TDFM) concepts.
This result clearly shows the relaxation process is dominated by time-dependent fracture energy, therefore we have to clarify the relationship between D and at in the near future.
In terms of the methodology of advanced time-dependent fracture mechanics, this paper developed an expert system to realize an appropriate combination of material database, condition database and knowledge database.
To comprehensively quantify the benefits of fibers in the presence of variable cement contents, time-dependent fracture and damage propagation were examined quantitatively utilizing a combination of macro-surface cracks, fractal analysis and both image monitoring and processing techniques.
In order to ensure long-term stability of structures in a rock mass, the study of time-dependent fracturing is essential.
In this article, the effects of tertiary γ′ on the crack-tip stress relaxation process, oxide fracture and time-dependent crack growth kinetics are treated in a micromechanical model which is then incorporated into the DARWIN® probabilistic life-prediction code.
37 38 We entered wrist fracture status and other potential risk factors as time dependent covariates, permitting wrist fracture values to be updated to account for changing status over time.
The results of this investigation are utilized to assess the effects of controlling grain size and γ′ size on the risk of disk fracture and to identify possible means for mitigating time-dependent crack growth (TDCG) in hot-section components.
This time-dependent crack growth regime is assisted by a significant creep damage as indicated by the large amount of intergranular decohesions induced by cavitation on fracture surfaces.
These changes are time dependent; the tissue surrounding the fracture haematoma matures during the early bone healing phase, supporting the healing process in a tightly correlated and sequentially determined course.
Aim of this study was the analysis of synovial protein concentrations following ankle dislocation fractures hypothesizing time dependent and specific regulation patterns including activation of complement components.
