And, due to the axial compression ratio, shear span ratio and the amount of reinforcement influence the shear capacity of the FRP materials.
With the advancement of science and technology, the development of civil engineering disciplines are largely depend on the application and development of new materials with excellent properties and new technologies.
Conclusion With the development of science and the progress of the society, the FRP materials will be more widely applied in the field of civil engineering.

Introduction As we know, heterogeneous materials such as rock or rocklike material have a composite or heterogeneous microstructure or texture, which can be seen with the naked eye or with a microscope at various magnifications.
Moreover, the behaviour of rock or rocklike materials and the growth of cracks or microcracks in rock or rocklike materials are strongly influenced by this heterogeneous microstructure.
Consequently, the numerical methods used for studying the fracture behaviour of rock or rocklike materials should take the heterogeneity into consideration.
Sum of elastic energy release (ERE) of the all elements is total elastic energy release of brittle materials occurred at current loading step.
