Introduction to Material Selection Matrix

Muhammad Abduh (

Being inspired by Material Requirements for Floaters Paper by Kvaerner on International Workshop on Advanced Materials for Marine Construction in New Orleans 1997, there is an opening to One Rule Material Selection:
– Material Property;
– Design Criticality

Why should there be one rule material selection?
– Wrong material is one of the root cause in engineering failures (OPS DOT, EGIG, HSE UK);
– Existing material selection guidelines (ASME B31 Series, Norsok, DNV, ASTM) are rather qualitative;
– Material decision become bias without quantitative judgment;

One Rule Material Selection Method
Approaches to one rule material selection have been provided:
– Material Properties Chart (Cambridge University and MIT), Figure 1
Chart that combine two properties of materials, e.g : density vs strength, density vs cost
– Material Selection Matrix
A more versatile selection tools that combine series of material properties with series of design requirements;


Figure 1. One of the material property charts (Material Engineering Cambridge University UK)

The ground for One Rule Selection Matrix, Table 1:
– Complete and detail material property database eg. mechanical properties, physical properties, corrosion properties, economic properties;
– Specification of design criticality to be provided by material design


Table 1. Collaboratory Requirements from Material Properties Provider and Design CriticalityProviders

Proposed One Rule Material Selection Matrix Methodology

1. Create Property Matrix (Ref. ASTM, AISI, PPI, In-House Testing)


2. Create Design Criticality, Set Maximum Design Value


3. Calculate Material Design Value

Material Design Value = [Steel Property Matrix] x [Design Criticality]

4. Set Priority Selection


5. Refine Design Criticality


6. Validate Result, refine design criticality, and recalculate material design value
