In forming of AHSS the temperature increase at die/sheet interface affects the performance of lubricants and die wear. This study demonstrates that Finite Element (FE) analysis, using commercially available software, can be used to estimate temperature increase in single as well as in multiple stroke operations. To obtain a reliable numerical process design, the knowledge of the thermomechanical properties of the sheet as well as the tools is essential. Using U-channel drawing the FE model has… 

Numerical and experimental study on determination of the contact temperature in an industrial ironing operation

Tribological conditions in forming operations depend on several parameters such as tool-workpiece interface pressure, surface expansion, sliding length, sliding speed, tool and workpiece materials

Temperature effects in deep drawing of advanced high strength steels

As advanced high strength steels (AHSS) find more use in automotive industry to meet crashworthiness and light weighting targets, concurrently. AHSS typically have higher strength, but lower

The realisation that the temperature in the stamping process plays an important and underestimated role is gaining recognition. In the ASPECT project [1] the implications of temperature on friction

Zoning Lubricant Die Application for Improving Formability of Box-Shaped Deep Drawn Parts

The ‘formability’ of sheet metal is a major keyword referring to process design in the sheet metal forming industry. Higher formability could reflect lower production costs and time. Many studies

Friction and lubrication play an important role in providing high quality parts from a deep drawing process. Friction conditions depend on sheet and tool material, surface qualities, the type of the

Computational analysis of the thermomechanical behavior of lightweight multifunctional photovoltaic sandwich structures

In this study, the thermomechanical behavior of multifunctional (photovoltaic/ aluminum core/ skin) sandwich structures is investigated numerically using the finite element simulation. Parametric



Forming of Al 5182-O in a Servo Press at Room and Elevated Temperatures

Aluminum alloys are increasingly used in automotive manufacturing to save weight. The drawability of Al 5182-O has been proven at room temperature (RT) and it is also shown that formability is

Evaluation of Lubricants for Stamping of Al 5182-O Aluminum Sheet Using Cup Drawing Test

Lubricants are necessary to avoid adhesion, galling, and scratching in aluminum stamping processes. In this study, various lubricants, including dry lubes and wet lubes, were evaluated using cup

The Heat Developed during Plastic Extension of Metals

When a soft metal, such as annealed copper or aluminium, is deformed while cold, either by stretching, hammering, rolling, or other method of ‘‘cold working’’ it hardens; that is, the forces

Fundamentals and Applications of Hot Stamping Technology for Producing Crash-Relevant Automotive Parts

Improving crashworthiness and reducing weight are two contradicting requirements in automotive industry. To fulfill both requirements, lightweight metals such as aluminum or magnesium, or high

A Realistic Friction Model for Computer Simulation of Sheet Metal Forming Processes

A realistic model for friction in lubricated sheet-metal forming which takes account of the different lubrication regimes which may occur at the sheet/tooling interface is developed. Friction is
