Introduction to the analysis of delamination related fracture processes in composites

This research concerns the analysis and prediction of delamination damage that occurs in composite structures on the sublaminate scale - that is, the scale of individual plies or groups of plies. The objective was to develop analytical models for fixed-mode delamination in composites. These include: (1) the influence of residual thermal and moisture strains; (2) local or transverse crack tip delamination originating at the tip of transverse matrix cracks; and (3) delamination in tapered composite under tensile loading. Computer codes based on the analytical models were developed and comparisons of predictions with available experimental and analytical results in the literature were performed

Synthesis of Thienopyridines and Isoquinolines from 6-Amino-1,2-dihydro-4-methyl-2-thioxopyridine-3,5-dicarbonitrile and of Phthalazines from Thieno[3,4-c]pyridazine

Thienopyridine 1 and thienopyridazine 13 have been readily reacted with electron-poor olefins to give isoquinolines and phthalazines, respectively. Some of the obtained compounds were tested for their antimicrobial activity
