“…The hat-shaped part was used by Yoshida-Uemori [ 17 ] for verification of their proposed hardening model which can describe the transient Bauschinger effect and workhardening stagnation which appears at reverse loading. The implementation of the Bauschinger effect and workhardening stagnation can improve springback prediction [ 18 , 19 , 20 ]. This shape is also present in reinforcement beams of doors and roofs of passenger cars made of materials with high values of yield and tensile strength.…”

Formability and its prediction of high-strength steels is an important research subject for forming specialists and researchers in this field. Springback and its accurate prediction of high-strength steels are very common issues in metal forming processes. In this article, the impact of blank holding force and friction on the parts springback made of dual-phase steel was studied. Numerical predictions of the springback effect were conducted using nine combinations of yield criteria and hardening rules. Results from experiments were evaluated and compared with results from numerical simulations. The use of lower blank holding forces and PE foil can reduce springback by a significant amount. Numerical simulations where the Yoshida-Uemori hardening rule was applied produced more accurate springback prediction results compared to simulations that used Krupkowski and Hollomon’s isotropic hardening rules in number of cases.

“…Correct inputs and parameters must be used in numerical simulation to obtain relevant results. In metal forming simulations four types of parameters exist that are vital for simulation accuracy [ 20 , 21 , 22 ]. These categories include tool design, forming process, material, and numerical parameters [ 19 ].…”

“…Thus, the bulge test is more suitable for description of the plastic properties of sheet metal at large deformations. This is crucial in determining the stress–strain behavior of steel sheets produced in cold-rolled conditions [ 9 , 10 , 11 , 12 , 13 , 14 ].…”

“…The mechanical and plastic properties of the materials are necessary input parameters for the finite element analysis (FEA) of forming processes. FEA is an established tool for the calculation and analysis of sheet deformation [ 13 , 14 , 15 , 16 ]. The simulation program should be efficient, accurate and easy to use [ 17 , 18 , 19 ].…”

To design a reliable forming process it is necessary to determine the mechanical and formability properties of the processed material, which are used as input parameters for forming simulations. High-strength steel is irreplaceable as a material for producing the deformation zones of current automobiles. This type of steel can be processed by conventional or unconventional forming methods. In the sheet forming process, the material is usually under uniaxial and biaxial stress. The bulge test is utilized for determination of biaxial stress–strain curves, which are often used as input material data for forming simulations. In this work, numerical simulations of bulge tests using TRIP RAK 40/70 steel were performed to study the impact of yield criteria and hardening laws on the accuracy of thickness prediction of the deformed steel sheet. Additionally, the impact of different solvers and integration schemes on the thickness prediction was tested. Furthermore, the impact of various degrees of deformation (various dome heights) on thickness prediction accuracy was evaluated. Numerical results showed a good correlation with experimental data. When the Hill90 yield criterion was used, the software with implicit solver was more accurate in predicting thickness compared to software with explicit integration scheme, in most cases. In addition, the thickness prediction of parts with lower deformation was more accurate compared to parts with greater deformation (higher dome height).

“…In particular, the comprehensive performance of the covering parts mold drawbead and its strengthening process are seriously lagging behind, which has become a key bottleneck in the research and development of automobile cover mold manufacturing. Therefore, there is an urgent need to improve the surface performance of the drawing tendons through surface strengthening technology and thereby improve the service life of automobile covering parts molds [ 1 , 2 , 3 , 4 , 5 ].…”

Effect of Laser Quenching-Shock Peening Strengthening on the Microstructure and Mechanical Properties of Cr12MoV Steel

The automobile covering parts mold is a key piece of equipment in the automobile industry, and its drawbead is the core element that affects the life of the mold and the quality of the parts made. Due to the complex structure of the mold cavity for covering parts, there exist differences between material flow characteristics, load conditions, stress strain, failure forms and so on in the surface of different parts of its drawbead and the different directions of the same part of the drawbead, thus putting forward new requirements for material strengthening. For the differentiated lose efficacy forms of the dangerous end faces of the tension bars, this study carried out research into the effect of laser quenching–shock peening strengthening (LQ-LSP) on the organization, plastic deformation resistance and wear resistance of Cr12MoV steel. It was shown that the microhardness (722.30 HV) and residual stress (−383.84 MPa) of the specimens were further enhanced after laser quenching–shock peening composite strengthening. The residual austenite content of the specimen was reduced to 0.8%, and the eutectic carbide distribution morphology was improved. After three rounds of laser composite peening, the specimens had the smallest displacement of the nanoindentation load–depth curve, which exhibited the greatest nanohardness (20.0 Pa) and modulus of elasticity (565.25 Pa), while reducing the coefficient of friction (0.61) and surface roughness (0.152 Ra). The smooth and flat surface of the specimen with shallow and narrow plow grooves improved the resistance of Cr12MoV steel to plastic deformation and wear.
