چکیده    A branch of human knowledge, which treats the behavior of cracked structures, is called fracture mechanics. since there is no intact structure in the world, then the paramount importance of fracture mechanics in human life is accentuated. the main parameter of fracture mechanics is called crack compliance, which is the amount of flexibility added to the flexibility of the intact structure due to the presence of a crack with specified size. the compliance, similar to flexibility, is the sole characteristics of the cracked structure. in this way for a given structure with a specified crack, there should be a single compliance. unfortunately, in classical fracture mechanics that is not the case! the number of crack compliances for a clacked structure is equal to the number of researchers who treated the case! this diversity in the results stems from the presence of epistemic uncertainty in the mathematical basis of classical fracture mechanics. in view of the need for remedy, the abdolrasoul ranjbaran team (art), investigated the case and proposed a reliable fracture mechanics, which is based on sound logical reasoning. the proposed reliable fracture mechanics is described in the presented paper. the paper is managed via fourteen titles as, introduction, the mathematical basis of the classical fracture mechanics, birthplace of the state based philosophy, strong form of governing equation, analytical solution by laplace transform, the weak form equation, the finite element equation, logical basis of the state based philosophy, state functions, persian curves, reliable crack compliance, energy release rate, stress intensity factor, and weight function for the stress intensity factor in sections one to fourteen respectively. the paper concludes with a list of cited references.
