Mechanical properties of an aluminum-filled epoxy
Technical Report
·
OSTI ID:6342869
A mechanical testing program has been carried out on an aluminum-filled epoxy. This material is used in the construction of stress gages that are used near underground explosions. The properties are needed to properly calibrate the gages. The block from which the test samples were taken was characterized by measuring density and ultrasonic compressional and shear wave velocities. Test types included hydrostatic compression, triaxial compression, uniaxial strain loading followed by uniaxial strain unloading, and uniaxial strain loading followed by biaxial unloading. The highest confining pressures reached were in the neighborhood of 700 MPa. The material was found to be nonlinear over the entire range of each of the investigated variables. The stress-strain response can be classified as nonlinear, plastic-hardening; there is no definite yield point. Hardening rates increase with increasing confining pressure.
