A Novel Ontology Approach to Support Design for Reliability considering Environmental Effects

Table 1

Typical environmental effects of atmosphere.

Environmental load	Typical material	Classification of environmental effects	Typical environmental effects
Temperature	MM	CEP	Metal resistivity change
	PM	CMP	Material expansion and deformation
		CEP	Insulation changes
Humidity	MM	CCP	Corrosion: increase the rate of chemical reaction
		CEP	Metallic conductivity changes
	PM	CMP	Reduce lubricant performance
		CEP	Electrical short circuit
Salt spray	MM	CMP	Block: wear and tear
		CEP	Metallic conductivity changes
	PM	CMP	Damage protective coating
		CCP	Corrosion

Notes:
MM: metallic materials. PM: polymer materials.
