... to understand the adhesive stress distribution, the shear and normal stresses were plotted in Fig. 12 as a function of distance from the delamination edge into the adhesive bond for a range of shear strength values. The adhesive shear stress is maximum at the tip and asymptotically reaches zero within a short...

... from reaching excessive temperatures in hot engine environments. Delamination of the TBC is the main problem of laser drilling acute angled holes in the coated components. The present study investigates the mechanisms involved in the development of the delamination cracks. A significant role of melt...

... examines the feasibility of depositing CoCrMo coatings on Ti substrates using Laser Engineered Net Shaping ® . Studies show that deposition of CoCrMo coating on a Ti substrate is very challenging, cracking and delamination being the major observations. Several alternative strategies, which may lead...

...M. S. Won; C. K. H. Dharan Previous studies have shown the severe limitations that have to be placed on machining forces when drilling composite laminates due to their propensity for delamination. Delamination, which consists of separation between the plys in a laminate, is due to the relatively...
