Measured using an Instron load frame with extensometers.
tension: 4” between grips
compression: cylinder (0.5” x 0.5”)
As the fragile PMB crush as strain increases, the modulus decreases with increasing strain and irreversible damage leads to significant hysteresis during subsequent ramps.
initial E = 2.5 MPa
