| 33. | Fracture toughness. The system allows the user to continue to measure the crack size (through the most extreme of the left and right sides of the crack) to calculate the fracture toughness. The system shows 3 more columns in the hardness measurement result table: C1, C2 and Kic. C1 is the distance from the most left end to the most right end of the crack (unit mm), C2 is the top to the bottom distance, the total crack length L = C1 + C2-D1-D2 (D1 and D2 are the measured indentation diagonal length), fracture toughness is calculated according to Kic = 0.0028 * sqrt (Hv * F / L), Hv is the measured hardness indentation, F is test force unit N, L unit m, Kic unit MPam ^ 1 / 2. Different calculation methods are provided later. Like the indentation, the crack size will be marked by a rectangle, the user can drag the rectangle to modify, and automatically update the calculation result statistics. In the statistics column, the fracture toughness selection is displayed. If checked, the statistical result is the fracture toughness Kic, and if not selected, Hv. Reporting (WORD and EXCEL) automatically adds the C1, C2, and Kic columns. Note: When using the fracture toughness, the above Nusi hardness should be unselected. |

Panoramic Scan
Select the "Set Scan Range" function under "Panoramic Scan", and select how to set the scan range (specify coordinates, rectangular vertices, multilateral vertices) and motion mode (accuracy first, speed first) on the "Set Panoramic Scan Range" interface as shown in the following figure. Scan range vertex setting When selecting rectangular vertices and multilateral vertices, please first go to the current video window to select the vertices by following the prompts, and then click the "OK" button to set the scan range. If the range is not set in the current video window, the "Set Panoramic Scan Range" window is closed, and the user should set the scan range first.
The software interface right-click menu provides the functions to move to the point, display the path, delete the selected path point, import the current image, save the image, and so on.
For the one-yuan coin on the XY automatic platform, set the scanning range of 2015mm for panoramic scanning. The HDS system controls the motor to move and captures the resolution of 640*512, and finally connects more than 2500 pictures into the effect picture shown in the following page.
Free Set the Scan Area
The scanning area function is set freely. For irregular samples, the scanning area can be set according to the test shape of the sample to narrow the scanning range, so as to save the scanning time and improve the work efficiency.
Multi-sample Panoramic Scan
Path Planning Operation On The Panoramic Image: click "Import to the current image" to import the image content displayed in the current panorama interface into the "Current Image", and conduct path planning operation in the "Current image" according to the operation instructions of the path planning function.
