Material Uncertainty Analysis (MUA)
Combines composite micro-mechanics and probabilistic analysis to
determine the reliability of a composite material/structure based on the
scatter of fundamental primitive variables. These variables include various
material constituent parameters (e.g., fiber and matrix stiffness and strength)
and manufacturing parameters (e.g., fiber volume fraction, void content, and
fiber architecture and ply thickness).
Determines the structural response sensitivity to constituent
material properties and other design variables including fiber architecture,
manufacturing tolerances and defect content.
Calculates the Cumulative Distribution Function (CDF) and
Probability Density Function (PDF) of the response and primitive variables over
the entire failure probability.
Probabilistic design of composite materials for aerospace and
Calculation of lamina and laminate allowables and design
variables based on given/simulated test data scatter.
Effective estimation of the influence of constituent properties
and manufacturing variables on the response of a composite material/structure.
Efficient determination of critical design variables prior to
test program start.
