    Abstract

    Solid mechanics is an interdisciplinary subject mainly deals with deformation of materials and structures under external loading conditions. In many applications, safety is an important concern. For instance, a small crack can cause catastrophic damage to an airplane which can result in loss of many lives. Moreover, such incidents can cause significant damage to the environment which might take years for complete recovery process such as the effect of oil spill due to a damaged tanker, corroded pipeline, etc. In order to prevent from such undesired incidents, several approaches are commonly followed within the solid mechanics framework. One common approach is to perform experiments to test the durability of materials and structures. Although such an approach can provide us realistic data, such experiments are not always possible and they are mostly expensive. Today, engineers and researchers commonly use theoretical or computational approaches as an alternative to analyse the problems that they are working on. Theoretical approaches mostly depend on various assumptions to simplify the calculations. Moreover, they are restricted to specific geometries and loading conditions. Hence, it is essential to use a technique which does not have such limitations and is also economically feasible. Computational techniques are very good candidates for this purpose and they are commonly used both in industry and academia.
