| Abstract |
In recent years, instrumented indentation technique has been widely applied in the mechanical characterization of hydrated soft materials such as hydrogels and bio-soft tissues. However, the indentation measurement technique and properties evaluation methods for this kind of materials undergoing large deformation have not been well developed. Applying the indentation load-relaxation experiments, this paper studied the relaxation behaviors of calcium alginate/polyacrylamide double-network hydrogels under large spherical indentation deformation. The effects of temperature on the relaxation properties of calcium alginate/polyacrylamide double-network hydrogels were also measured and evaluated. This work not only helps to improve the understanding of the relaxation properties of double-network hydrogels under large deformation conditions, but also has certain guiding significance for the development of the instrumented indentation testing technology of soft materials. |
