Manual on Experimental Methods for Mechanical Testing of Composites

References Liquid-metal strain gages can be fabricated in either single- or delta-rosette configurations. Their main advantages are their low stiffness (essential for 1. Beatty, M.F. and Chewning, S. W., "Numerical Analysis of the Reinforcement Effect of a Strain Gage Applied to a Soft use on composites with soft, elastomeric matrices) Material," Int. J. Eng. Sci., 17, 907-915 (1979). and high elo...
