Inverse problems of inhomogeneous fracture toughness using phase-field models [PDF]
, 2022 We propose inverse problems of crack propagation using the phase-field models. First, we study the crack propagation in an inhomogeneous media in which fracture toughness varies in space. Using the two phase-field models based on different surface energy functionals, we perform simulations of the crack propagation and show that the $J$-integral ...

Experimental investigation on mode II fracture performance of old-new concrete [PDF]
Archives of Civil Engineering, 2022 The old-new concrete interface is the weakest part in the composite structure, and there are a large number of microcracks on the interface. In order to study the mode II fracture performance of the bonding surface of old-new concrete, the effect of ...

The fracture toughness of soft tissues [PDF]
Journal of the Mechanical Behavior of Biomedical Materials, 2012 Fracture toughness is important for any material, but to date there have been few investigations of this mechanical property in soft mammalian tissues. This paper presents new data on porcine muscle tissue and a detailed analysis of all previous work.

Effect of Testing Method Type and Specimen Size on Mode I Fracture Toughness of Kimachi Sandstone
Journal of MMIJ, 2019 Several testing methods have been proposed for evaluating the mode I fracture toughness of rocks. Since the fracture toughness evaluated from the different testing methods is generally not compared, what is still not wellknown is the effect of the ...

Three-dimensional buoyant hydraulic fracture growth: constant release from a point source [PDF]
Journal of Fluid Mechanics, 950, A12 (2022), 2022 Hydraulic fractures propagating at depth are subjected to buoyant forces caused by the density contrast between fluid and solid. This paper is concerned with the analysis of the transition from an initially radial towards an elongated buoyant growth -- a critical topic for understanding the extent of vertical hydraulic fractures in the upper Earth ...
