About
This application facilitates unconfined compression tests by wirelessly connecting to a GCTS Wireless Point Load Testing System. It automates specimen height measurement, data recording, and calculation of compressive strength, stress, strain, and Tangent Modulus. Results can be emailed as CSV files or saved for later viewing.

FAQ
What is Unconfined Test used for?
Unconfined Test is used to perform and record data for unconfined compression tests on soil or rock specimens. It works in conjunction with a GCTS Wireless Point Load Testing System to automate measurements and calculations.
How does Unconfined Test measure specimen height?
After placing a calibrated specimen in the apparatus, the application automatically measures the specimen's height once a small threshold load is applied. This height measurement is crucial for the subsequent test calculations.
What calculations does Unconfined Test perform?
The application automatically calculates the unconfined compressive strength, stress, and strain of the specimen during the test. It also calculates the Tangent Modulus at 50% strength and provides a real-time display of the loading rate.
Can I export my test results from Unconfined Test?
Yes, after performing a test, you can easily email the data directly from the application as a CSV spreadsheet. This allows for convenient sharing and further analysis of your results.
Does Unconfined Test require a GCTS Wireless Point Load Testing System?
Yes, Unconfined Test must connect once to a GCTS Wireless Point Load Testing System via Bluetooth before it can be used. This connection is essential for the application to function and record test data.
How accurate are the results from Unconfined Test?
The application makes automatic corrections for frame deformation compliance, giving the frame a "Virtual Infinite Stiffness." This ensures that all presented results are extremely accurate.
What devices is Unconfined Test available on?
Unconfined Test is available for iPhone and iPod devices. It requires a Bluetooth connection to the GCTS Wireless Point Load Testing System to operate.
How often is Unconfined Test updated?
The last update for Unconfined Test was on December 5, 2019, with version 1.32. The application was initially released on August 10, 2015.
