Introduction Numerical modelling and simulation of behaviour of material samples and engineering structures made from cement-based composites, under mechanical, thermal, etc. loads, including their reinforcement, as steel fibre one, with the aim of suppression of undesirable tensile stresses, corresponding to relevant experimental characteristics, can be seen as a massively important research field, namely because of the danger of creation of micro-fractured zones, followed by potential initiation and evolution of macroscopic cracks.
Their deeper study in the near future is necessary, due to its practical significance, connected with the durability and life cycle of engineering structures.

In principle, there are repair requirements for all composite structures which applied in engineering field [1].
In the actual operation of civil aircrafts, a variety of damages, for example: hole damage, will be generated inevitably in the composite structures, and there is necessary to repair without delay.
Obviously, a feasible method for engineering application for damage tolerance analysis and repair tolerance analysis of damaged composite structures was provided through these analyses.
The maximum error listed in Table 5 is 7.18%, it is enough satisfactory for most engineering applications.
