Advanced optical High-Speed testing: Investigations of materials and components utilizing High-Speed camerasAdvanced optical High-Speed testing
 
Systèmes de mesure: ARAMIS, PONTOS
 
Keywords: High-Speed Tensile test, crash, drop test, cell phone, machine tool, process optimization
 
When determining material characteristics, optical measuring techniques provide a larger validity range, particularly with respect to plastic deformation. Higher demands on crash safety in the automotive industry and on the dynamic behavior of other products require high-speed optical solutions because there, no sensor technology is exposed to the high speeds or accelerations.
Improved Determination of Yield Stress for Sheet Metal MaterialsImproved Determination of Yield Stress for Sheet Metal Materials
 
Systèmes de mesure: ARAMIS
 
Keywords: True stress, true strain
 
The material characteristics of sheet metal material to be used, for example in the design of a new car, have to be determined and specified precisely and reproducibly in a test laboratory. An important magnitude to describe the material behaviour during the forming process and in case of a crash is the yield stress.
Determination of Process Limitations in Sheet Metal Forming - Forming Limit DiagramDetermination of Process Limitations in Sheet Metal Forming - Forming Limit Diagram
 
Systèmes de mesure: ARAMIS
 
Keywords: Forming Limit Curve (FLC), Forming Limit Diagram (FLD), material characteristics
 
The forming limit diagram (FLD) offers the chance to determine process limitations in sheet metal forming and is used in the estimation of stamping characteristics of sheet metal materials.

Systèmes de mesure: ARGUS, ATOS
 
Keywords: Measuring instrument, Sheet metal, 3D digitizing, Material properties
 
During recent years, optical measuring technologies in sheet metal forming and tooling have been used more and more in the industry. Main applications are the digitizing of metal sheet parts and tools, forming analysis of metal sheets as well as the determination of material properties. Good interfaces to conventional CAD/CAM and numerical simulation systems made such optical measuring systems a part of complex process chains. These process chains mainly focus on optimizing the development of products and production processes and on improving the product quality. Using optical systems considerably decreases the development time for products and production while improving the quality.
ARAMIS and the detection of flow behaviour for sheet metal material in high speed tensile testARAMIS and the detection of flow behaviour for sheet metal material in high speed tensile test
 
Systèmes de mesure: ARAMIS
 
Keywords: Flow curve, high speed camera
 
Information about the flow behaviour of material is important for crash- and forming simulations. The flow behaviour can be described by the true stress strain curve.
