Tīmeklis2015. gada 15. okt. · Lamellar tearing is a cracking phenomenon which occurs beneath welds, and is principally found in rolled steel plate fabrications. The tearing always lies within the parent plate, often outside the transformed (visible) heat-affected zone (HAZ), and is generally parallel to the weld fusion boundary. TīmeklisDexter and Melendrez (2000) demonstrate that W-shapes are not susceptible to lamellar tearing or other through-thickness failures when welded tee joints are made …

Tīmeklis2016. gada 28. jūn. · T-joints and corner joints are two basic joint designs that are subject to lamellar tearing [ 1 ]. Such joints experience high restraint because weld thermal contraction is opposed by compressive forces from the base metal [ 1 ]. Excessive stress in plate results in material separation at inclusion–matrix interfaces. Tīmeklis2004. gada 1. dec. · Lamellar tearing is a type of weld cracking which occurs in a joint on which a large restraint stress acts in the direction of the plate thickness (hereafter …
TīmeklisA lamellar tear takes place in three stages. In initiates by separation and void formation at inclusions in the base metal. The second stage of tearing is the formation of crack "terraces" by the linking together of individual separations.
