The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Effects of temperature-dependent material properties on welding simulation (2002, background): “Recently, Lindgren [10] gives a detailed review on this topic, which includes the development of material constitutive relationships, material microstructures and material properties as functions of temperature.”
Numerical simulation to study the effect of tack welds and root gap on welding deformations and residual stresses of a pipe-flange joint (2005, background): “These simplifications are necessary due to both lack of data and numerical problems when trying to model the actual high-temperature behaviour of the material [18].”
Using finite element and ultrasonic method to evaluate welding longitudinal residual stress through the thickness in austenitic stainless steel plates (2013, background): “These simplifications are necessary because of both lack of data and numerical problems when trying to model the actual high-temperature behavior of the material [13].”
Influence of welding sequence on welding distortions in pipes (2008, background): “These simplifications are necessary due to both lack of data and numerical problems when trying to model the actual high-temperature behaviour of the material [18].”
