Three-Dimensional Laminate Media Analysis
Material Input Window
Click
on the thumb nail for larger image
The material properties window is where the user assigns the
various properties to the material(s) used in the analysis.
The materials will save and load to a *.mat file for
constant material properties.
The number of materials used
in the analysis is entered on the top left. The drop
down menu gives known material properties for LAM3D. The Apply
to Material option has a number to the right. By pressing the Apply button
the material properties selected in the drop down menu are applied
to that particular material ID.
The load and save button can be used to load and save
a material to a *.mat file in their currently working directory.
The program will load and save a material pertaining to the Material
ID being selected. In the window shown above, clicking the save button
will save mat. ID 1 to a *.mat file while clicking the load button
will populate Mat ID 1 with the material properties from your *.mat
file.
All materials can be can be edited, loaded and saved
while the program is running to actively explore potential materials
for the laminate design being studied. You will be "warned" in the error
window (bottom right on main window) if there is an empty
cell in this table. Some Empty cells can cause crashes depending
on the property left empty.
Materials Properties Table
The following are the inputs used for the constant material
property window. All units are imperial units. (Metric units can
be used if all units throughout the program are input in metric form)
E1,E2,E3: Young's moduli along the principal ply
directions (psi).
v23,v13,v12: Poisson's Ratio in 2-3, 1-3, 1-2 direction respectively.
G23,G13,G12: Shear Moduli in 2-3,1-2,1-3 planes respectively (psi).
a1,a2,a3: Coefficient of thermal expansion
Failure Criteria Table
X1T: Tensile strength of material in principle
(1) direction (psi).
X1C: Compressive strength of material in principle (1) direction (psi).
X2T: Tensile strength of material in principle (2) direction (psi).
X2C: Compressive strength of material in principle (2) direction (psi).
X3T: Tensile strength of material in principle (3) direction (psi).
X3C: Compressive strength of material in principle (3) direction (psi).
