In FEMdesigner, material properties are specified in simple text files, following an easy-to-understand format.
In this template, for the units specified [in brackets] on line 1, the corresponding
material property units required are listed [in brackets] following the material
property variable.
Text following a semicolon (;) is comment text, except for line 1, where it will be used as the material label when assigned to a FEMdesigner part.
E2, G2, Phi, and CTE2 are used to specify orthotropic material properties. Please see diagram provided in Help for graphical description of orthotropic material properties orientation.
Material file layout template:
[m, mm, in];Material ID (ID required - will be displayed in FEMdesigner)
E [Pa, MPa, psi] ;Young's modulus for isotropic materials, for
;direction 1 in orthotropic materials
Nu [no units] ;Poisson's ratio
CTE [1/°C, 1/°C, 1/°F] ;Coefficient of Thermal Expansion
Rho [kg/m^3, kg/mm^3, lbf/in^3] ;Density
T [m, mm, in] ;Plate thickness
E2 [Pa, MPa, psi] ;Young's modulus in direction 2 for orthotropic
G2 [Pa, MPa, psi] ;Shear modulus in direction 2 for orthotropic
Phi [degrees] ;angle between direction 1 and global x-axis
CTE2 [ 1/°C, 1/°C, 1/°F] ;CTE in direction 2
Y [Pa, MPa, psi] ;Yield Stress, tension
UTS [Pa, MPa, psi] ;Ultimate Tensile Strength
L [cycles] ;Endurance limit
C [Pa, MPa, psi] ;Yield stress, compression
