New Approach to Edge Crack Sensitivity Characterization

Edge crack sensitivity plays a major role in characterizing materials used in vehicle components important for energy absorption during crashes. This seminar will introduce and demonstrate a method, that can be performed by a single tensile testing machine. A series of tensile tests uses pre-notched sheet metal specimens and analyzes the systematic behavior with different notch depths. A special tool is used by the tensile testing machine and applied to the notched specimen before the standard tensile test is performed.

ZwickRoell Testing Solutions for Concrete-Reinforcing Steel 

Reinforcing steel is essential in the construction of buildings and infrastructures. As it is a safety-relevant component, the mechanical properties of its products are defined by various national and international standards. These mechanical properties have to be tested by the individual producer and a certified lab. This webinar will give an overview of the innovative testing solutions for static and fatigue testing of concrete reinforcing steels.

New Repeatable and Reliable Edge Crack Sensitivity Test Methods

Recent developments in new forming steels show that forming processes used for these materials must look more closely at material behavior. Sensitivity to edge cracks during the forming process is one important characteristic. There are several approaches to learning more about edge crack behavior. This webinar will present new methods developed thus far.

ZwickRoell Testing Solution for Hole Expanding Test to ISO 16630

The hole expansion test is a test method applied in the metalworking industry and is used to determine the ductility of the edges of punched sheet metal. In the case of high strength steels, forming technology presents new challenges due to the formation of edge cracks. In order to make manufacturing processes more reliable, characteristic values for edge crack sensitivity are determined using the hole expansion test. This webinar will give an overview of this solution for sheet metal testing machines.

The New HIT750P for Charpy Impact Testing

Notched impact strength is an important characteristic in applications for pipeline construction and ship building and can be determined with Charpy specimens in pendulum impact testers. The test method is described and defined in the international standard ISO 148-1 and in ASTM E23. In this webinar, you will learn about ZwickRoell's newest pendulum impact testers, their functionalities and advantages.

New Device for Bending/Hemming Test to VDA 238-100:2017

Standard bending tests are generally easy to handle and simple to evaluate. A more sophisticated bending test must be used when evaluating advanced steel and aluminum alloys and their forming processes for the automotive industry. The VDA 238-100 is a guideline and an automotive industry internal standard procedure that qualifies sheet metal material for specific forming processes. The guideline describes a bending or hemming test that requires a mechanical device that is very stiff. The webinar will introduce the requirements in detail and the technical solution developed based on years of experience in this particular area. In addition, options for optical evaluation of the tests will be presented.

Comfortable and Reliable Hardness Testing from Nano to Macro

Hardness testing is the most applied test within the mechanical testing of metals. Hardness testing machines must fulfill a number of requirements if precise and accurate results are desired. The numerous scales – which are equivalent to the various hardness testing methods – means there are a wide range of hardness testing machine types and a multitude of interesting applications. This seminar will give a brief but comprehensive overview of our portfolio.

Safe and Reliable Advanced High-Strength Steel (AHSS) Testing

Advanced high-strength steels are the favorites in automotive applications where lightweight construction is required. Moreover, tensile testing of these steels remain the most important tests. However, the high strength of these materials is also linked to a high surface hardness. Therefore, the gripping technique must be improved to avoid premature wear. In this live demo, we will present the ideal testing equipment for the safe and reliable testing of AHSS

Easy Handling and Reliable Results with Strain Rate Control Method A1 and A2

Strain rate control is now the standard testing method for metals tensile testing. Due to the sensitivity of forming material, tensile testing results using controlled strain rates are more stable and more reproducible, which was and is an important requirement of the automotive industry and industries involved in metal forming. This live demo will show how precise strain control is and the differences are between the two methods, A1 and A2, which are strongly recommended by ISO 6892-1.
