Collier Research HyperSizer v7.3: Structural Sizing & Optimization Software

HyperSizer v7.3 is Collier Research Corporation’s CAE software for stress analysis and sizing optimization of composite and metallic structures, originally developed at NASA and used throughout the aerospace industry for design and certification .

Core Capabilities

Structural Optimization

HyperSizer couples with FEA solvers (Nastran, Abaqus, ANSYS, OptiStruct) to optimize panel and beam cross-sections, material systems, and laminate layups. The software typically achieves 20–40% structural weight reduction while ensuring manufacturability .

Failure Analysis & Certification

The software automates hundreds of industry-standard failure methods, generating stress reports required for FAA certification. It replaces manual spreadsheets and “hand calculations” with automated, auditable documentation .

Composite Laminate Design

HyperSizer defines laminate zones, optimizes ply coverage and stacking sequences, and minimizes ply drops across sizing boundaries to reduce fabrication complexity and cost .

FEA Integration

HyperFEA automates iterative coupling with FEA solvers, updating stiffness terms and load paths until convergence, evaluating millions of design candidates without remeshing .
