Study on Hyperelasticity of Photosensitive Resin Plate

The work aims to study the hyperelasticity of photosensitive resin plates and analyze their mechanical properties. The compression experiments were carried out on different photosensitive resin plates, and the stress-strain data were obtained, whichwere fitted byMooney-Rivlin constitutive model. The fitting curve, material parameters C-10, C-01 and fitting curve residual value of MooneyRivlin constitutive model was obtained. Conclusion Mooney-Rivlin constitutive model can well fit the material's hyperelastic relationship, and the plate's deformation degree is directly proportional to the hardness, which provides a theoretical basis for the study of the deformation of the flexographic plate.
