In this paper, shear fracture
tests of shear pins were conducted firstly, and then a linear model and a bilinear model were established.
Based on the fracture criterion above, it can be judged only whether the tensile fracture or the shear fracture
occurs while the developing degrees of the fracture cannot be determined.
S] are the equivalent plastic strain in equibiaxial tension/ compression at shear fracture
and f is an orientation dependent parameter.
Based on our case report, the mechanism for associated ankle and talar body fractures involves the adduction force of the supinated foot, which causes a shear fracture
of the medial malleolus followed by an axial load on the dome of the talus.
Among his topics are classical fracture mechanics approaches, lattice geometry and the structure of cement and concrete, the fracture of concrete in tension, combined tensile and shear fracture
of concrete, a four-stage fracture model, and multiscale modeling and testing.
Moore and Lockner (1995) used confining pressure to create a shear fracture
in a granite cylinder so as to study the microcrack pattern that related to the deformation.
As discussed above, this shift of the RA value implies also the shift between the tensile and shear fracture
modes; actually this is the sequence of the cracking modes within a typical fatigue specimen of this kind.
8a), and few chunks are remained on PA6 side after shear fracture
The mechanisms that initiate the fracture are shear fracture
, cleavage fracture, and intergranular fracture.
The remainder of the rupture shows the crystalline appearance of a tensile or shear fracture
under extreme stress concentration.
It showed an isolated shear fracture
of the trochlea without any bony associated lesion of the elbow.
