发帖数: 8 | 1 A hyperelastic material with stain energy relation:
W=c*exp(a*I1^2+b*I2]
where a, b, c are constants, and
I1=e11+e22+e33
I2=e11*e22+e22*e33+e33*e11-e12^2-e23^2-e31^2
(From Fung's biomechanics of living tissue)
I read ANSYS theory manual, didnt' find a hyperelastic model that I can use
directly. Actually, I am not sure the hyperelastic models already there. If
there is one I can use approximately. | i******t
