Q&A
Granta Design—innovating since 1994
What does Granta do for Lightweight Design?
1. Materials data management• Consistent information company-wide• Ensure accuracy, security, traceability…• Deploy for use in design – CAD, FE, CAE…
2. Reference data• Composites, light alloys, plastics, natural
materials…
3. Specialist tools• CES Selector• Hybrid Synthesizer

Drivers
CES Selector for lightweight design
Transportation: Reduction of carbon footprint
Reduced fuel consumption
Increased performance
Building & construction: Lower loads on support structures
Reduced foundation work
Lower transportation & construction costs
Weight reduction techniques Materials with high specific strength or stiffness
Hybrid materials & structures
Selection of Materials
When?
Which lightweighting strategy? Influence on design? Development & qualification costs?
Early identification of viable solutions Communication of trade-offs
Challenges?
Increasing:TimeEffortCost
Design brief / requirements
CADPreliminary design concept
CAD, CAEOptimisation
packages Detailed design
Final design
Prototype & testing
LCA
Selection MethodologyAll Materials
Breakdown design requirements into:
Function – What does the component do?
Constraints – What essential conditions must be met?
Objectives – What is to be maximized or minimized?
Screen on constraints - ‘Go’ / ‘no-go’ criteria (usually many)Rank on objectives - Ordering of materials that ‘go’
Supporting information – Specialist databases, contact suppliersLocal conditions – Preferred suppliers, process location & capability
Top Candidate Materials
Final Selection
ExhaustiveSystematic Auditable
Key components:
• Complete & comparable data
• Performance indices
Case Study
Constraints:• Adequate toughness & strength• Temperature resistance (-40°C to +85°C)• Durable to rain and salt water• Manufacture from flat sheet/profile
Function:Self-supporting ‘Intermediate’ floor for train carriage
Panel loaded in bending Stiffness-limited design Length, width specified Thickness free
Objectives:• Minimize mass• Minimize cost
Aim:• Evaluate ‘standard’ materials• Investigate sandwich panels
