Determination of the Stress–Crack Opening Relationship of SFRC by an Inverse Analysis

  • Published:
Mechanics of Composite Materials Aims and scope

Quantifying the residual stresses σ fr in tension is one of the most critical issues in the theory of steel-fiber-reinforced concrete (SFRC). The objective of this investigation is to determine the stress–crack opening relation of SFRC. An inverse technique is proposed for the determination of σ fr by employing experimental data from three-point bending tests on notched members. The nonlinear finite-element analysis program ATENA is utilized to verify the stress–crack opening relation obtained. A comparison of simulated load–crack tip opening displacement curves with experimental data attests to the adequacy of the inverse technique.
