Assuming that failure is induced when the normal and shear stress components on the fracture satisfy the Mohr–Coulomb failure criterion, we can develop an expression for the specimen strength as a function of βw, the angle between the major principal stress and the normal to the fracture. ...
Fig. 32. A flow chart for failure and strength analysis of a composite structure. 2.4 Elastic modulus formulae The five elastic moduli of a UD or uniaxially aligned short fiber composite are expressed as follows (Huang, 2018; Huang et al., 2019) (32)E11=Vf+VmA11E11fEmVfEm+VmA11E11f...

A reference point is defined at the center of the bolt hole and then the end beam restraints are considered as a beam, using the contact pairs between the elements at the two opposite sides of the built-up sections. Figure 3 shows the existing interactions between the bending frame ...

First, the majority of points were removed using proportion of variance local descriptors, then a deep learning algorithm was applied to identify candidate rock bolt points. For a TLS scan, CFBolt resulted in a precision of 98.2%, recall of 98.7% and F1 score of 98.5. Mapping and evaluating...
A variation on the ‘she bolt’ system is the taper tie which is a long tapered bolt that is passed through the wall. It has different sized threaded nuts and waler plates to each end. After use, the entire taper tie is removed and re-used. The load capacity is governed by the diame...
