摘要：NOVELTY - The assessment method involves performing lossless detection and standard stretching experiment; obtaining full-plastic coefficient; drawing a relation curve and calculating the defects size to impact a factor according to predetermined formula; establishing an inefficient assessing curve to calculate the position of the breaking points; confirming the plastic breaking degrees of the pressure apparatus and the cracking inefficient degrees; and judging the safe state of the pressure apparatus containing crack type defects. USE - Method for assessing safety of a pressure apparatus containing crack type defects. ADVANTAGE - Assessment method is easy and convenient to use for the calculation of any material, and produces more accurate assessment. DESCRIPTION OF DRAWING(S) - The drawing shows the flowchart of the method for assessing safety of a pressure apparatus containing crack type defects. (Drawing includes non-English language text).
