Abstract

Abstract

Unstable fracture toughness is used to analyze size, boundary effect and crack propagation of concrete.Both size effect, boundary effect formula for unstable fracture toughness and crack propagation formula with real physical meaning and realistic rule are presented.Based on which, formulas for predicting the equivalent strength of unilater interval induced joint are proposed, in which these coupling effects on the equivalent strength are considered.The comparisons of the predictions given by the present model with experimental data prove that the model of the paper is efficient and accurate.
- unilater interval induced joint,
- equivalent strength,
- size effect,
- boundary effect,
- effective crack propagation,
- unstable fracture toughness
