Regularized Yeoh Material For Compressible Rubbers
The following strain energy density is used.
where and are material constants. and are reduced invariants of the right Cauchy-Green deformation tensor.
The above command takes input list of arbitrary length (, excluding tag).
If the number of double inputs is odd, the last one is interpreted as density.
If the number of double inputs is even, the density is assumed to be zero.
The first half of double inputs is read as and the second half .
The following command shall be used.
The following command shall be used.
For , let and , the strain energy density is
If density is nonzero, say for example , then the following command shall be used.
For , let , , , , and , the strain energy density is
