Critical engineering components in the process of designing have employed fail-safe approaches and damage tolerance in industry optimization intelligent processing. Different types of geometrical intricacies were occurring in designing of pressure vessels while considering the parameters. The failures may be due to manufacturing defects or pre-existing flaws present in the cylinder. Even in the probabilistic method of determining failure the structural integrity of the components changes on compressive and tensile loadings. The failures cause the pressure vessels in not adopting its design for the requirement. Normally Inherent Flaw Models (IFM) was used to design wide tensile specimens effectively since the fundamental aspects of material failure can be assessed. DL based Inherent flaw models (IFM) was utilized to generate Failure Assessment Diagrams (FAD) and also to estimate the notched tensile strength of different cracked geometry. IFM is limited only of the wide through cracked tensile specimens. The present work utilizes modified IFM and by converting the pressure vessel failure design data to that of a wide tensile plate by changing its equivalent crack length obtained from an axial crack present in the cylinder. Failure pressure estimation based on fracture criterion is found to be a good coincidence with the data series. Finite Element Analysis (FEA) procedures were utilized to determine plastic zone size of the plate for better validation of the results. Crack Initiation and subsequent growth were identified from the plastic zone.

在设计过程中的关键工程组件在工业优化智能处理中采用了故障安全方法和损坏容限。在考虑参数的同时，设计压力容器时会出现不同类型的几何复杂性。失效可能是由于气缸中存在制造缺陷或预先存在的缺陷引起的。即使采用确定故障的概率方法，部件的结构完整性也会因压缩和拉伸载荷而变化。故障会导致压力容器无法按照要求使用其设计。通常可以使用固有缺陷模型（IFM）有效设计宽拉伸试样，因为可以评估材料破坏的基本方面。利用基于DL的固有缺陷模型（IFM）生成失效评估图（FAD），并评估不同裂纹几何形状的缺口抗拉强度。IFM仅限于破裂的宽拉伸试样。本工作利用改进的IFM，并通过改变从气缸中存在的轴向裂纹获得的等效裂纹长度，将压力容器的失效设计数据转换为宽拉力板的设计数据。发现基于断裂准则的失效压力估计与数据序列具有很好的一致性。利用有限元分析（FEA）程序确定板的塑性区大小，以便更好地验证结果。从塑性区识别出裂纹萌生和随后的增长。
