When is creep significant in the materials In general in tem

When is creep significant in the materials? In general, in temperatures above 0.4 the melting temperature. In general, in temperatures below 0.4 the melting temperature. In general, in axial stress above 0.4 the yield stress. In general, in axial stress below 0.4 the yield stress.

Solution

creep is formed due to elevated temp and constant stress

so by options we can creep is significant at above 0.4 melting point

Option 1
