DESCRIPTION:Tape-springs are thin\, transversely curved strips\, of which 
 the carpenter’s tape measures is a familiar everyday example. When you b
 end a tape-spring\, it initially deforms uniformly\, before suddenly formi
 ng a highly curved “fold” region: an example of elastic localisation. 
 The curvature in the fold and unfolded regions are governed by the Maxwell
  equal areas construction – familiar from thermodynamics – applied to 
 the tape-spring moment-curvature relationship. In our recent work\, we hav
 e introduced “tapered-springs”: tape-springs with varying cross-sectio
 nal geometry along their length. When bent\, we observe novel spiral-shape
 d folds and “jumping” behaviour. Key to understanding this behaviour i
 s the fact that the Maxwell equal-areas construction must be satisfied spe
 cifically on the propagating fronts of the fold
