Abstract—Gelatin blended with carboxymethylcellulose (CMC) scaffold was fabricated via freeze drying method. The various gelatin and CMC ratios were 100/0, 90/10, 80/20, 70/30 and 60/40, respectively. The mechanical characterization of the scaffold was done by compressive test using universal testing machine. The obtained data was used to determine compressive modulus and shear modulus which was analyzed from neo-Hookean model. The deformed scaffold and total strain energy time response were analyzed using finite element model (FEM). The scaffold G73T showed the highest value both compressive modulus (0.53±0.11 kPa) and shear modulus (1.02±0.11 kPa). The results were consistency with FEM that G73T showed the highest range of equivalent elastic strain and the highest value of total strain energy-time response. The results could imply the best condition for scaffold fabrication from mechanical analysis which might suitable for tissue engineering applications.
