3、Brief introduction of yes300 software for dynamic stress-strain testing system

Main operation interface of yes300

 The data collected in dynamic stress-strain experiment mainly include time and voltage of each channel. Yes300 program processes the original data, and its main functions are as follows: According to the graph in the image, the initial position of the stress wave in each channel is manually captured, and all the data in the required time interval are separated. According to the specific calculation method, the original data is analyzed and the initial position of stress wave is identified automatically. When the initial position of the stress wave deviates, the data of the stress wave can be moved so that the initial positions of the two are aligned. For the voltage in the effective time interval, the corresponding strain, stress and other parameters are calculated according to the given experimental parameters. For a given data list, the specified mapping relationship can be displayed as a plane curve. By default, the abscissa value is represented by time data and the ordinate value is represented by other data columns. You can edit the display style of the mapping curve, including linetype, lineweight, color, display interval, shape, size, color, display interval, etc. You can edit the style of the coordinate axis, annotation box, drawing border and other elements, including the name of the coordinate axis, the data range of the display range, the display position of the annotation box, whether to hide the border, whether the drawing border is hidden, and whether the grid guide is displayed. It can realize the functions of graph / image scaling, moving, grabbing, bitmap conversion, etc. Zooming and panning change the display range of the curve, and grabbing can get the corresponding value of the clicked image. Bitmap conversion is about to transform into bmp format bitmap and output.

Automatically capture the waveform and calculate the result automatically

the dynamic compression, tension, torsion, bending, shear and other items are calculated, and the dynamic stress, strain, strain rate, strain energy, particle velocity and other data are obtained
