摘要: Hydrogels are promising materials for bioengineering applications, and good model the study of hydrated biological tissues. As these often have a structural function, measurement their mechanical properties is fundamental importance. In present gelatin gels reinforced with ceramic microspheres produced poroviscoelastic response in spherical indentation studied. The constitutive responses unreinforced determined using inverse finite element modeling combination analytical estimates material parameters. behavior composite assessed by both numerical homogenization. results identification parameters show that it possible to obtain representative without need additional tests. agreement between experimental on predictions from homogenization adopted tools capable providing particle-reinforced hydrogels.
