Material Recommendation - Step 4

Before proceeding to steps 5-6 it may be appropriate to consider additional material characteristics including:   

Relative Impact Resistance/Toughness  
Dimensional Stability  
Regulatory/Agency Compliance 

Materials with higher tensile elongation, Izod impact and tensile impact strengths are generally tougher and less notch sensitive for shock loading applications (See Table 1).
