This article discusses the possibility of using a finite-element-based inverse design method to evaluate a technology for making parts by cold sheet stamping. It examines the process of reengineering in the software suite PAM-STAMP. The results that are obtained provide information on the development of the product and different pre-computed fields: stress-strain state, thickness reductions, defects, etc. © 2013 Springer Science+Business Media New York.

The casting of a large steel globe-cock plug is examined to illustrate the use of computer modeling to find zones where macro- and micro-porosity are concentrated. The article discusses the key aspects of the problem's formulation in ProCAST software, presents modeling results, and compares the defects that are found by modeling with experimental data obtained in a foundry. © 2013 Springer Science+Business Media New York.

The article examines the use of the software suite ESI SYSWELD to calculate the strength of joints formed by spot welding. The process of spot welding (SPW) is always important in those fields of engineering where it is necessary to join thin sheet-like parts that differ from one another in geometry and spatial position. Developing a process for this type of welding requires knowledge of metallurgy, the theory of strength, and the theory of heat exchange, which complicates the process's design and execution. The engineering firm ESI Group offers the design software suite SYSWELD, which is based on the finite-element method. Since the parts that were being modeled had planes of symmetry, only half of the geometric models were used in the computations of tensile and shear strength. The welding problems (heating, fusion, and cooling) were solved on two-dimensional models with the use of axial-symmetry conditions.

This article presents an example of the end-to-end simulation of the casting of a steel ingot in an ingot mold and solid forging of the ingot. The simulation is performed using the software products ProCAST (ESIGroup, France) and QForm (Quantor Form, Russia). The formulation and solution of problems is examined and data are obtained on the temperature field and shrinkage defects of the ingot. The effects of these factors on the metal-forming operation are taken into account in the solution of the problems. © 2014, Springer Science+Business Media New York.
