Material Uncertainty Analysis (MUA)

View Product Datasheet (PDF)

Product Highlights:

·         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.

Applications/Benefits:

·         Probabilistic design of composite materials for aerospace and automotive industries.

·         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.
