For Mij, there are three components available as input. The ply material pro- perties can be obtained either from the default values of fiber and matrix or from the user input. When user saves data the software uses relevant input informa- tion, formulates plate analysis problem, and solves it to give all six stresses and strains as output. For each step of the plate analysis, mentioned above, the user is given the option of viewing the input data for that step. This module uses simple beam theory applied to the laminate beams.
Loading is in the form of uniform lateral loading per unit length along the length of the beam.
The input to the module consists of geometry of the beam, loading, boundary condi- tions, material properties and stacking sequence. The material property input and lamina sequence sections are similar to the Plate Edge loading section. The output for the module is in the form of numerical values for stresses, strains and graphs maximum stress through the thickness and deflection along the length. Various boundary conditions are available. This module analyzes a rectangular box beam by making use of laminate analysis and beam theory.
