As soft physical gels become more popular due to their biological applications, there is increased interest in measuring mechanical properties such as toughness. However, traditional tensile testing methods do not work for such materials due to the intrinsic softness of the material. We present a novel method for measuring fracture energy using a rheometer and show it is broadly consistent with the pure shear test, a standard method where the material exhibits mode I fracture. This method has potential applications in characterizing a wide range of soft and transient gels.
