Composites enable light, stiff, and corrosion-resistant structures. But they are also brittle and sensitive to defects, manufacturing variation, and local damage. That makes it harder to predict strength, fatigue life, and safety margins with confidence. Lifetime is highly load-sensitive. A small load increase can cut life dramatically, which can turn a promising concept into a high-risk product if fatigue, bonded joints, and stability are not handled correctly.

Composites also fail in multiple independent modes. Outside aerospace and wind, design guidance is often limited, and teams risk either over-engineering with slow iterations or under-engineering with late-stage surprises.

With CREADIS, you get composite analysis that matches the criticality of your structure. We combine our in-house AUTOLAYUP method with a classification matrix (low, moderate, high) to apply the right level of verification. A working model for design iterations is typically ready in less than a day, so decisions can be made early and refined fast.

Our Structural composites, engineering and analysis services include:

• Layup design: fibre orientations, stacking sequence, thickness variation, and ply drops
• Ultimate strength: fibre failure, inter-fibre failure (Puck), delamination, debonding, and core shear
• Fatigue: along fibres and in shear, including crack growth in bonded joints
• Stability: global and panel buckling, and face-sheet wrinkling
• Bonded joint design and verification
• Design for quality assurance, inspection (UT), and repairability
• Standards support: IEC 61400-1/-5, ASTM F2291, F3598, and F1193 (including technical expert participation in the ASTM sub-committee updating F1193 for composites)

Toolchain: CREADIS AUTOLAYUP, ANSYS ACP with CREADIS additions, and ANSYS Mechanical

With the right analysis at the right time, your team can iterate faster from concept onwards, optimize mass, cost, and stiffness, and avoid both over- and under-engineering. Together, we help you bring composite structures to market with predictable performance and robust verification for real industrial environments.
