I created a handy tool to calculate the area of a hysteresis loop and its equivalent viscous damping. Though the calculation isn’t particularly complex, repetitive tasks can become tedious sometimes. This software can compute the complete cycles of a hysteresis loop, the area of each cycle, and the equivalent viscous damping corresponding to each cycle. The equivalent viscous damping is calculated using the following formula,

\[{h_{eq}} = \frac{\Delta A}{4\pi \cdot A}\]Where: $\Delta A$ is the area of the hysteresis loop, and $A$ is the area of the shaded triangle OAB.

With the formula above, we can quickly calculate the equivalent viscous damping,

### Download and Installation

The software is compatible with Windows (x32, x64) platforms: **DOWNLOAD**

### Basic Operation

The software accepts text files with two columns of data, separated by commas, tabs, spaces, carats (^), or slashes (/). The following separator styles are supported,

The graphical area supports both keyboard and mouse operations:
