On the Assessment Mode of Some Safety Coefficients Using Breaking Polynomial Criteria

Abstract

Abstract Starting of the characteristic expressions of some breaking polynomial criteria, known and used in practice, it is highlighted how to assess the safety coefficients used in some practical cases. It is obvious that the decision belongs to the user given the experience in the adequate technical domain. In this regard it must not neglect the fact in that the breakage is produced most often in unpredictable moments, conditioned by multiple factors, dependent on material, on manufacturing technologies of finished products, respective the operating conditions.
