For components made of ductile materials, finite element approaches which incorporate material damage con titutive models are able to predict the failure behaviour and the corresponding process with high accuracy. However, these local approaches suff

The pressure vessel and piping components may be subjected to operation in the ductile-to-brittle transition regime of the material due to increase in the transition temperature. This increase can be due to irradiation embrittlement, vario s other ma

In this work, we have assessed the results of the local and nonlocal versions of Rousselier’s damage model, which have been used here for simulation of ductile crack growth. There are several issues regarding the accuracy of the results which has b

Dissimilar metal welded joints are integral parts of modern-day power and process plant equipments. Among the various types of material combinations, welded joints of ferritic grade carbon–manganese steel and austenitic stainless steels are very co

Safety analysis of critical components and the overall plant is a major and important task in the field of mechanical engineering. Therefore, it is essential to know the allowable loads and the corresponding failure behaviour (e.g., crack initiation,

Numerical analyses based on local damage models are often found to depend on the spatial discretisation (i.e., mesh size of the numerical method used). The growth of damage tends to localize in the smallest band that can be captured by the spatial di

Dissimilar welds impose a challenge to the engineers concerned with the structural integrity assessment of these joints. This is because of the highly inhomogeneous nature of these joints in terms of their microstructure, mechanical, thermal, and fra

In this study, the classical Gurson—Tvergaard—Needleman (GTN) model has been extended to a non-local form using damage parameter ‘ d’ as a degree of freedom in the finite-element (FE) formulation. The evolution of the non-local damage is rela

Cleavage fracture toughness data often exhibits a considerable amount of scatter and strong dependencies on temperature, loading rate, pre-straining, etc. due to the highly localized nature of the failure mechanism and microstructural inhomogeneity i

It is now widely recognized in literature that the results of the local damage model are mesh dependent. Regularization methods which use gradients of equivalent plastic strain in the material yield function are also popularly known as gradient plast
