Method for calibration of parameters assessing brittle fracture of material based on beremin model |
| abstract |
A method for the calibration of parameters assessing the brittle fracture of a material based on a Beremin model: choosing at least two samples having different degrees of constraint, calculating the fracture toughness K 0 of each sample at the same calibrated temperature at an accumulated failure probability of 63.2% respectively by using data of a fracture toughness test on each sample; measuring the stress-strain profile at the calibrated temperature to establish a finite element model of each sample, and calculating the maximal main stress and unit volume of each unit in each sample under a loading of K 0 ; giving a different value to the Weibull slope rate m and calculating a Weibull size parameter σ u of each sample, and plotting the relationship curve between m and σ u of each sample; and obtaining the parameters assessing the brittle fracture of the material according to the coordinates of the intersecting point of the m - σ u curves. In comparison with conventional methods for calibration of parameters based on a toughness-translation Beremin model, the method has a smaller amount of calculation and can illustrate intuitively the convergence process of the calibration. |
