Resumo :
|
|
ABSTRACT. IN THIS WORK THE BOUNDARY ELEMENTS METHOD APPLIED TO CRACK GROWTH ANALYSIS IS PRESENTED. THIS INCLUDES INCREMENTAL CALCULATIONS OF STRESS INTENSITY FACTOR AND CRACK GROWTH PATH. AFTER EACH INCREMENT THE STRESS INTENSITY FACTOR IS CALCULATED BY J-INTEGRAL TECHNIQUE USING BOUNDARY ELEMENTS METHOD. THE CRACK GROWTH PATH IS EVALUATED, INCREMENTALLY, USING THE MAXIMUM CIRCUNFERENCIAL STRESS CRITERIA.
KEYWORDS: BOUNDARY ELEMENTS, COMPOSITES, FRACTURE MECHANICS, PROPAGATION.
