Welding is a major manufacturing process that joins two or more pieces of materials together
through heating/mixing them followed by cooling/solidification. The goal of welding …

The welding process is the basic technique of joining in the shipbuilding industry. This
method generates welding distortions that cause a lot of problems during the manufacturing …

The purpose of this study is to investigate the effect of the lumped passes simulation on the
distribution of residual stresses before and after heat treatment in a thick-walled nuclear …

Steel I-girders with corrugated webs have been widely used in the past decades, especially
in bridges. Although, there are several specialities in their structural behaviour which needs …

Unwanted distortions are typically observed in components after the welding process.
Physical trial tests and extra post-treatments are being widely utilized in industries to …

In this study finite element simulation approaches (lumping and prescribed temperature) are
implemented to study residual stress distribution in a welded box type structure. This …

Local and highly nonuniform heating during welding and subsequent cooling cause
complex thermal cycles inducing residual stresses and deformations in the weldment. There …

The plasticity-based distortion prediction method was improved to address the
computationally intensive nature of welding simulations. Plastic strains, which are typically …

Two distortion modeling methods, mapping plastic strain and lump-pass modeling, were
developed and validated for predicting distortion on large welded structures to reduce the …

In August 2023, the International Maritime Organization (IMO) issued the Revised
Guidelines for the Reduction of Underwater Radiated Noise from Shipping to Address …
