A design is provided comprising a set of design variables including a thickness for each of the zones, and a ply percentage for each orientation angle for each of the zones, each ply percentage identifying a percentage of plies within a zone having a particular orientation angle.The design is modified in a series of iterations, each iteration including: analyzing the current design by calculating an objective function, a set of ply evolution constraint functions each indicating a degree of ply continuity between a respective pair of adjacent zones, and one or more structural constraint functions; performing a sensitivity analysis by calculating partial derivatives of the objective function for the current design with respect to a selected set of the design variables, and calculating partial derivatives of the constraint functions for the current design with respect to a selected set of the design variables; and generating a new design by determining an optimum update of the design variables in accordance with the analysis and the sensitivity analysis."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of designing a composite panel","description":"A method of designing a composite panel, the panel comprising a plurality of zones, each zone comprising a plurality of plies of composite material, each ply in each zone having a respective orientati","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8494813","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
