WebJul 12, 2013 · Test for low-temperature crack-bridging ability An economical and practical method was developed to test the crack-bridging ability of coatings at a low temperature. 3 Refinement is needed before this method could be considered as an industry standard, but the following summarizes the prototype equipment and testing: 1. Web5 Repeating this analysis for paths 5, 6, and the connecting traction-free crack surfaces is identical to Rice [1968], and thus de nes a second path-independent integral: J root= J(x) x>x (10) Finally, considering paths 3, 4, and the partially traction-loaded crack surfaces leads to a connection between Jtip and J J root= Jtip + W B(x ) (11) which is simply a … hongky.com
