“…The state of the art of the (FAD) contains epistemic uncertainty, that should be modified. The current authors research team detected the need for remedy and after extensive research (Ranjbaran, 2010;Ranjbaran et al, 2013;Ranjbaran and Ranjbaran, 2014;Ranjbaran et al, 2020a;2020b;2020c;2020d;2021;Amirian and Ranjbaran, 2019;Baharvand and Ranjbaran, 2020), in the last two decades, proposed the Change of State Philosophy (CSP) which digested in the Persian Curves (PC) (Ranjbaran et al, 2020a), that is used for the development of a reliable (FAD). The validity of the work is verified via concise mathematical logics and comparison of the results with those of the others as follows.…”

A conventional tool for assessing the integrity of structures containing flaws is, the Failure Assessment Diagram (FAD). The (FAD) is a combination of the limiting conditions for load, the flaw size and fracture toughness or yielding stress. The abscissa is the load ratio and the ordinate is the toughness ratio. The toughness ratio is defined as a function of the load ratio. Three options are available for this function. The (FAD) drive is based on parameters of fracture mechanics. Classical fracture mechanics contains epistemic uncertainty and is unreliable. As a result, the state of the art for the (FAD) is also unreliable. The present authors' team, conducted an extensive investigation in the past two decades, which led to the birth of the change of state philosophy that is digested in the Persian Curve. In the present paper the Persian Curve is used for development of a reliable (FAD). The validity of the work is verified via concise mathematical logics and comparison of the results with those of the others.

This paper presents the details of an analytical investigation which was carried out to propose Persian curve. The curve provides an alternative of probability functions to define the state of a system. The Persian curves are super functions of the state variable which includes state functions and two control parameters. The state variable is a scaled identification parameter of a system. The state functions are two specific functions of the state variable. The control parameters are determined from the real-world data. Since the Persian curve has the basic properties of the probability function, it is called the Persian probability function. It is concluded that all natural phenomena are certain and the lack of knowledge has led the humans to divide the phenomena into certain and stochastic categories. The proposed Persian curve was validated by analysing the probability data from different fields of study.
