Dynamic Crack Propagation Problems of Fibre-Reinforced Concrete

Abstract EN

Applying the built dynamic crack model of fibre concrete, bridging fiber segment is substituted by loads.

When a crack propagates its fiber continues to break.

By the approaches of the theory of complex functions, the problems dealt with can be translated into Riemann-Hilbert problems.

Analytical solutions of the displacements, stresses, and dynamic stress intensity factors under the action of of moving variable loads Px2/t2 and Pt3/x2, respectively, are attained by the ways of self-similar measures.

After those analytical solutions are utilized by superposition theorem, the solutions of arbitrary complex problems can be obtained.
