This summary of doctoral dissertation deal with modeling of fracture in various 2D structures. The standard experimental specimens with defects, which are used in evaluation of fracture parameters, are investigated numerically in this work. The original FE generation technique based on the adaptive approach is developed for the 2D structures with defects. The stress indicator employed in the adaptive analysis is able to capture high gradients of stress in the vicinity of the defect. Performance of this technique is checked against the defects of different geometry. Finally the above-mentioned technique exposes its suitability for solving fracture problems.
