DOWNLOAD & INSTRUCTIONS
1. Download the App
The app is a standalone application which can be installed on windows systems. There is no need for additional applications or systems in order to execute the application. Download the app by clicking the button:
2. Install the App
After downloading the app can be installed on any windows system. Since the app has been created using matlab, a matlab runtime has to be installed.
3. Input Data
The required input for calculating the collapse curve consists of the geometry of the cross section of the beam, elastic material properties and the material strength.
4. Calculation of the Curve
After the input of the required data, a neural network calculates the collapse curve for the given set of data. The neural network itself has been trained using many nonlinear FE-calculations of different parameter combinations.
5. Output
The output consits of the collapse curve as well as the maximum bending moment and the angle at the maximum bending moment.
6. Restrictions
Beam width a: 20-100 [mm]
Beam hight b: 20-100 [mm]
Thickness t: 0.5-4 [mm]
Beam length: 100 [mm]
Materials investigated: S235, S355MC, S460MC, H800, 6082T6, 5086O, 6061T62, 6063T7
