Mechanical parameters of the resin specimens.

Specimen ID	Millistrain at peak stress	Peak stress (MPa)	Ave. stress (MPa)	E (GPa)	Ave. E (GPa)	Strain 50	Stress 50	E50 (GPa)
R1	29.86	26.48	24.92	0.89	0.92	11.71	13.24	1.13
R2	25.19	24.41		0.97		10.87	12.21	1.12
R3	26.29	23.85		0.91		11.90	11.93	1.00

Strain50 refers to the strain value when the stress reaches 50% of the peak stress value. Stress50 refers to 50% of the peak stress.
