The undesirable residual stress accumulated in the parts during the melting and
solidification of the metal powder layer by layer retards the further application of the selective …

The improvement of thermal efficiency of power plants has provided the incentive for the
development of the martensitic–ferritic 9–12% Cr creep-resistant steels. Good progress has …

A method for modeling the effect of stress relaxation at high temperatures during laser direct
energy deposition processes is experimentally validated for Ti-6Al-4V samples subject to …

In this study, the weld residual stresses (RS) in a 25 mm thick ferrite steel plate with newly
developed low-temperature transformation (LTT) welding wire were investigated by finite …

In light of the demand for reducing the emission of climate-damaging gases such as CO 2, it
is very important to apply lightweight materials in the aerospace and automotive industries …

Constitutive plasticity theory is commonly applied to the numerical analysis of welds in one
of three ways: using an isotropic hardening model, a kinematic hardening model, or a mixed …

Three plate joints, namely, single-pass weld, double-pass weld, and four-pass weld were
fabricated using P92 steel. The hole-drilling strain-gauge method and X-ray diffraction …

The present work investigates the effects of stress state and crystallographic orientation of
the principal stress axes on the growth behaviour of micro-voids embedded in an aluminium …

Numerical finite element analyses were combined with experimental observation of a single-
pass autogenous beam weld in SA508 Gr. 3 Cl. 1 ferritic steel. Two weldment sets were …

The double-ellipsoidal heat power density model proposed by Goldak, has been widely
used as the basis for modelling heat transfer in arc welding operations for more than thirty …
