The differences in the slopes of curves indicate the different elastic properties of the structures. (parksystems.com)
For example, researchers could use the sound waves to measure elastic properties of cells in a petri dish, seeing how they respond to forces. (sciencedaily.com)
«With this method in hand, we're able to show that time - resolved measurements of elastic properties on dynamic materials are possible on short timescales.» (sciencedaily.com)
