Material Modeling and Data Integration for Composites
HDfOS helps engineering teams manage complex composite materials by consolidating test data, literature values, and supplier specifications in one environment. This integration ensures that each laminate uses consistent material definitions, reducing risk caused by outdated or conflicting information. Unified material models support both classical lamination theory and modern progressive damage analyses.
Within the Material Explorer, users can define ply-level properties, failure criteria, and temperature-dependent curves. The platform guides users through required inputs, highlights missing data, and suggests conservative defaults when needed. This structured approach accelerates model creation while maintaining traceability to source data.
Design Workflows and Layup Definition
Designers use HDfOS to translate architecture requirements into viable layup sequences. The Stacking Designer enforces manufacturability rules, such as maximum ply angles and thickness transitions, to avoid impractical solutions. Early feedback on feasibility supports faster design iterations and fewer late-stage changes.
HDfOS also manages stack sequence versions, so design changes are tracked and linked to specific programs or projects. Users can compare alternative layups side by side and evaluate stiffness, mass, and margin-to-failure metrics. This capability is critical when balancing performance targets with cost and production constraints.
Simulation-Driven Validation Workflows
Integrated solvers in HDfOS allow engineers to run linear and nonlinear analyses directly on composite models. Progressive damage simulations reveal how cracks initiate and propagate through plies, enabling more realistic predictions of ultimate strength and residual stiffness. Accurate boundary conditions and load cases ensure that simulation results reflect real-world behavior.
Advanced users can leverage scripted workflows to automate repetitive tasks, such as parameter sweeps or batch simulations. Results are stored in structured format, making it straightforward to generate design reports and update trade studies. This level of automation is essential for programs that evaluate many composite configurations under varying conditions.
Compliance and Certification Support
HDfOS includes dedicated compliance modules that map simulation outputs to aerospace and automotive certification requirements. Built-in checklists guide users in producing the evidence needed for structural approval, covering topics such as allowable loads, testing levels, and documentation trails. Consistent workflows help programs meet both internal standards and external regulatory expectations.
The Compliance Dashboard highlights open items, such as required test correlations or pending reviews, so that teams can manage certification activities proactively. By linking analysis results directly to compliance tasks, HDfOS reduces administrative overhead and supports auditable decision-making throughout the product lifecycle.
