How to Download and Use ConWep Software for Blast Effects Analysis
ConWep is a software tool that calculates a range of blast effects from different types of high explosives and weapons, including blast loads, fragment penetration depths into concrete and steel, concrete wall breaching, projectile penetration into rock and soil, cratering, and ground shock. ConWep is based on empirical formulas derived from experimental data and field tests. ConWep can be used for various applications, such as structural design, vulnerability assessment, risk analysis, and blast mitigation.
How to Download and Use ConWep Software for Blast Effects Analysis
In this article, we will show you how to download and use ConWep software for blast effects analysis. We will also provide some examples of ConWep applications and results.
How to Download ConWep Software
ConWep software is made available through the Corps of Engineerâs Protective Design Center (PDC) at Omaha, Nebraska. You can download ConWep software from the PDC website[^1^]. You will need to register and create an account to access the download link. The registration is free and only requires your name, email address, organization, and country.
After you register and log in, you can find the download link for ConWep software under the Software & Tools tab. The current version of ConWep is V2.1, which was released in 2019. The file size is about 10 MB. You can download the software as a zip file and extract it to your preferred location on your computer.
How to Use ConWep Software
ConWep software is a standalone Windows application that does not require installation. You can run ConWep by double-clicking on the ConWep.exe file in the extracted folder. You will see the main window of ConWep as shown below:
The main window of ConWep consists of four tabs: Airblast, Fragment Penetration, Cratering/Ground Shock, and Projectile Penetration. Each tab contains different input parameters and output options for different types of blast effects calculations.
To use ConWep software, you need to select the appropriate tab for your analysis and enter the required input parameters. The input parameters include the type and amount of explosive, the distance and orientation of the target, the material properties of the target, and other factors that affect the blast effects. You can also select the units of measurement for your inputs and outputs.
After you enter the input parameters, you can click on the Calculate button to perform the calculations. The results will be displayed in graphical or tabular form on the right side of the window. You can also export the results to a text file or copy them to the clipboard for further analysis.
Examples of ConWep Applications and Results
ConWep software can be used for various applications involving blast effects analysis. Here are some examples of ConWep applications and results:
Airblast calculations: ConWep can calculate free-field and reflected blast pressure histories from free-air and surface burst explosions, average peak pressure and impulse from a hemispherical surface burst on a specified reflected wall area, peak pressure from a buried explosion, blast pressure in tunnels, and quasistatic pressure history from a vented internal explosion. For example, you can use ConWep to calculate the free-field blast pressure history from a 33 megaton (Mt) nuclear bomb detonated in the atmosphere at an altitude of 4 km and a distance of 30 km from the target[^3^]. The result is shown below:
Fragment penetration calculations: ConWep can calculate fragment penetration depths into concrete and steel targets for different types of 04f6b60f66
