The objective of the project is to create a biaxial loading device to test marine grade elastomers. The device should be able to apply constant load at a uniform rate to the test specimen in the positive and negative X and Y directions. The maximum load that should be able to be applied is two hundred pounds. The specimen size to be tested is three inches by three inches. The set up should allow for viewing of the specimen by a camera so that a digital image correlation (DIC) analysis may be performed. A sensing element is to be attached to the system in order to read exactly how much force is being applied at a given moment, and at what rate it is being applied. A user interface will be implemented to output this data digitally. The specimen that is being subjected to the loads will be attached to the rest of the system by using roller grips to clamp the material down. While the grip will be connected to the sensor, the sensor will then be attached to the back wall of a platform that will be made. The platform will be moved by an actuation system in order to apply the loads to the specimen. The target limit for how far the actuators will be able to translate is five inches. A code will be written in Visual Basic in order to keep all four actuators moving at the same rate. The budget for the entirety of the system cannot exceed five thousand dollars. The frame of the system is to be limited to a footprint of around three feet by three feet. Of the five subsections identified, four were completed.
