Orthotropic2D

 

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).
