Book Description
Finite Element Analysis of Weld Thermal Cycles Using ANSYS aims at educating a young researcher on the transient analysis of welding thermal cycles using ANSYS. It essentially deals with the methods of calculation of the arc heat in a welded component when the analysis is simplified into either a cross sectional analysis or an in-plane analysis. The book covers five different cases involving different welding processes, component geometry, size of the element and dissimilar material properties. A detailed step by step calculation is presented followed by APDL program listing and output charts from ANSYS. Features: Provides useful background information on welding processes, thermal cycles and finite element method Presents calculation procedure for determining the arc heat input in a cross sectional analysis and an in-plane analysis Enables visualization of the arc heat in a FEM model for various positions of the arc Discusses analysis of advanced cases like dissimilar welding and circumferential welding Includes step by step procedure for running the analysis with typical input APDL program listing and output charts from ANSYS.

Book Description
Welding is globally used as the most versatile means of joining all commercial metals. In fusion welding, a weldment is locally heated by the welding heat sources. Due to the nonuniform temperature distribution during the thermal cycle, incompatible strain leads to thermal stresses, the main source of problems. Thermal stresses in the weld may lead to formation of hot cracks. Therefore, it becomes necessary to develop a model for the welding process, which would produce not only qualitative but also quantitative information on thermal stresses. In the present work, a finite element simulation of the welding process, yielding the welding induced thermal stresses in rectangular weld pool, is presented.

Book Description
Annotation Finite Element Method (FEM) is a well-established numerical technique for analyzing the structural behavior of mechanical components and systems, as well as for use in solving problems in heat transfer, fluid flow, and electromagnetic potential. The method has become increasingly popular in recent years due to rapidly evolving, sophisticated, affordable software that can be easily run on a desktop computer. This two volume work will cover the basics of solid FEM modeling as well as advanced applications in structural dynamics and probabilistic design analysis. The second volume builds on the fundamental topics in volume 1, with coverage of more advanced types of finite element modeling, including dynamic analysis and finite element modeling of composite materials. It also covers design optimitzation and APDL programming. Tutorials are offered using ANSYS for further exercise and practice.

Book Description
Analytical models of the gas tungsten-arc welding process into finite element computer programs provides a valuable tool for determining the welding thermal cycle, weld bead shape, and penetration characteristics, as well as for evaluating the stresses and distortions generated as a result of the temperature transients. The analysis procedures are applicable to planar or axisymmetric welds with arbitrary cross-sectional geometries, under quasistationary conditions. The method used for determining temperatures features an iteration procedure to accurately account for the latent heat absorbed during melting and liberated during solidification of the weld. By simulating the heat input from the arc to the workpiece by a normal distribution function, temperature transients, weld bead dimensions, and cooling rates are evaluated as functions of both the magnitude and distribution of heat input, weldment geometry, and weld speed (or duration of heating for stationary arcs). Modeling of the welding thermal cycle is a prerequisite to analytical treatments of metallurgical changes in weld metal and heat-affected zone material, residual stresses and distortions, and weld defects. A quasistationary formulation for moving welds enables temperatures to be calculated using a two-dimensional heat conduction computer program. The present limitation of high welding speed can, however, be relaxed without altering the two-dimensional framework of the procedure.
