The orthotropic material is applied to shell4.
• E1 is the direction of local node 1 and 2.
• E2 is the vertical direction of E1.

• Young's Modulus 1 (E1): Defines the Young's modulus of the orthotropic in local direction by local node 2 to local node 1.
• Young's Modulus 2 (E2): Defines the Young's modulus of the orthotropic in local direction by local node 4 to local node 1.
• Shear Modulus (G): Defines the in-plane shear modulus.
• Poisson’s Ratio 1 (): Defines the passions ratio. Note that
• Damping Ratio (): Defines the damping ratio. The structural damping ratio of element and the damping matrix of is C computed from the following equation.
where:
: Damping Matrix
: Stiffness Matrix
: Damping Ratio
•Use User-defined Transverse Shear Modulus: Defines the transverse shear modulus. If this check option is disabled, shear correction factor is used to obtain the transverse shear modulus, which is a default value for original orthotropic material (~V9R2). If checked, user can set the transverse shear modulus.
• Transverse Shear Modulus 1: Transverse shear modulus in direction 1 (G1z).
• Transverse Shear Modulus 2: Transverse shear modulus in direction 2 (G2z).
• Stress-strain matrix (E)
