Sentence examples for modulus contrasts are from inspiring English sources
Fracture configurations influenced by three different elastic modulus contrasts are analyzed with other parameters staying the same, and the elastic modulus of barriers is, respectively, 5, 20 and 35 GPa larger than that of the pay zones.
Adjacent pay zones and barriers with high in situ stress contrast, high tensile strength contrast, low elastic modulus contrast are able to prevent the communication of fractures along the height direction and increase the fracture length and width.
Also, adjacent pay zones and barriers with high in situ stress contrast, high tensile strength contrast and low elastic modulus contrast are able to effectively prevent the communication of fractures along the height direction and lead to the increase of fracture length and width, and so does the barriers with large thickness.
The contrasts are intriguing.
Bulk modulus, Young's modulus and shear modulus are interlinked via Poisson's ratio : Poisson's ratio expresses the relationship of the relative thickness change to the relative length change of a material under the action of an external force.
a Elastic modulus contrast: 5 GPa, b elastic modulus contrast: 20 GPa, c elastic modulus contrast: 35 GPa Open image in new window Fig. 16 Variation of fracture width and length with different elastic modulus contrasts between pay zones and barriers.
The contrast was intriguing.
Due to the dynamic nature of ARFI excitation, lesion contrast is temporally-dependent. Contrast of spherical inclusions is highest immediately after force cessation, decreases with time postforce and then reverses, due to shear wave interaction with internal boundaries, differences in shear modulus between lesions and background and inertial effects.
Sometimes contrast is nice.
In contrast, for stresses generated by externally applied loads, the flat plate-matrix interface is always unstable as long as the plate modulus and the matrix modulus are different.
