Enables real-time monitoring of the material behavior under stress. Suitable testing schemes include, but are not limited to: cracking, material fatique, tensile testing and creep.
To comprehensively understand the behavior of different materials, it is required to learn how the breaking starts and how it
evolves. The breaking process iniates with rapid micro-scale events that have been difficult to detect prior to FlexRHINO DynaMat. Even the most challenging processes can now be measured and analyzed in real-time.
The benefits of FlexRHINO DynaMat
Pre breaking monitoring. FlexRHINO DynaMat visualises the fast changes in the material, like crack initiation, in microstructure scale: it can detect the cracks before they emerge.
Fully optical measurement. FlexRHINO DynaMat is completely based on optical devices, and no contact with the material is required: it is an ideal tool when high temperatures, pressures or chemical stress’s are involved.
High temporal dynamics. Some testing schemes may take days or weeks and yet, the interesting events may be as short as 100 µs: the FlexRHINO DynaMat analyses the information in real-time, and only saves the interesting events.
Wide material range. The FlexRHINO DynaMat can be used to monitor any crystalline material. Please contact ProtoRhino to see how your process is suitable.
Material breaking in detail
The material breaking starts by the changes on the microscopic level. The FlexRHINO DynaMat allows you to see these changes.
The FlexRHINO Dynamat provides a valuable advantage
In any material testing, the FlexRHINO DynaMat offers information beyond traditional means: it detects microscopic plastic changes in structures before the cracks are formed.
The benefits of FlexRHINO DynaMat technology
The material breaking emerges gradually, sometimes far below the specified yield strength. The damage may develop through multiple mechanism: e.g. via a microscopic crack formations or lattice dislocations, often preceded by a slip band. The events are fast with durations from 100 µs to 1 ms while the interval between events is often measured in seconds.
With the FlexRHINO DynaMat, monitoring these rapid changes on the material surface is now possible. Thanks to FlexRHINO DynaMat advanced image processing algorithms, the data can be analysed in real-time and the measurement can continue indefinitely.
Fatigue occurs when material is subjected to a cyclic loading. While the loading is under the yield strength of the material, microscopic plastic changes can still occur. These changes may lead to cracks, which in the beginning are often microscopic in size, but will eventually grow and lead to material failure.
Fatigue is typically a slow process and in the early phase the changes are only observable within the microscopic scale. Furthermore, the damage can take years to develop, but the microscopic plastic changes happens in time scales of less than a millisecond. Thus, predicting when and where the fatigue failure will appear was until now impossible.
The FlexRHINO DynaMat allows observing the initialisation and propagation of fatigue in real time.
In Tensile test the material is a subject to a controlled stress until a fracture occurs. The stress and strain development provides information of the yield strength and the ultimate strength of the material. Beyond elastic region, phenomena such as strain hardening and necking, provide additional insights to the fracture process.
Unfortunately, the material properties thus acquired, do not directly relate to the fracture formation: far before the material begins to yield, microscopic plastic deformations already occur, weakening the material. The stress-strain test is not sensitive to, and therefore cannot detect, these deformantions.
Cracks are almost without an exception initiating on the material surface and are thus detectable online with FlexRHINO DynaMat.
Creep is a slowly emerging plastic deformation of material under an intermediate perpetual stress. Creep damages are micro-structural changes, e.g. cavities and micro cracks, which while accumulating over time, lead to structural failure.
To evaluate material creeping behaviour, detection of both initiation and propagation of the creep damage is absolutely instrumental. This is however problematic, since on the macroscopic level, the plastic deformations masks the microscopic changes taking place..
The FlexRHINO DynaMat completely ignores the macroscopic deformations and detects events on the microscopic level. It unveils how the creep damage initiates and propagates during the creeping process.
Lighter materials means less fuel consumption, less pollution and better performance.
Thorough material testing is a key for safer journeys. FlexRHINO DynaMat leaves the guessing out of the equation.
Current development leads to higher speeds and forces. This requires new materials and testing methods. High performance means high responsibility.
Our choices affect the generations to come. More efficient solutions can be found through new materials.
