... acceptance criteria such as a dent depth. They are very conservative and their main advantage is to allow assessments in very short time period. " Level 2 " assessments are based on analytical/empirical models supported by full scale testing. In principle, they cannot be used outside the conditions...

... project document, PDAM (Pipeline defect in assessment manual). The primary inputs for the analysis are the tensile strength, the cyclic pressure and the dent depth. Figure 4 shows the typical dent with its critical dimensions. Representative equations for the dented life estimation are shown in equations...

... subjected to combined loading. The use of grout to repair specimens was found to inhibit a growth in dent depth under axial loading and restore the capacity of the dented member to a level greater than the undamaged strength. A comparison with existing and modified analytical methods for strength prediction...

... for estimating the load vs. dent depth response of tubular members subjected to "knife-edge" loading was developed. The load-deformation behavior is given by a three- term series whose coefficients are readily determined from the geometric and material characteristics of the member. The method is based...
