Fig. 3: Stress simulation of the elastic lines in compliant joints.
From: An auxetic meta-structure enabled soft locomotive robot
A Stress distribution in one of the joints when the elastic line is not pre-stretched, with a rotation angle of 56 degrees. B Stress distribution in one of the joints when the pre-stretched length of the elastic line is 1.5 times its original length, also at a rotation angle of 56 degrees. C Stress curves of the elastic lines in the joints under different pre-tension conditions during the contraction process of a 2 × 2 configuration SAS.
