I have designed a sheet metal bracket from 4mm stainless steel 304. There is a load on one of the corners that causes a 0.4mm deflection. I think this is OK right now, but I am concerned about creep (material straining over time). Will that 0.4mm stretch to 2mm in 10 years time? :shock: Does anyone know a simple way of calculating creep of a material? By the way, the force applied to create the deflection is 200N, and the temperature range the part will see over its lifespan is between -40 to +80degrees Celcius (I know that this kind of info is important for creep issues) Any help would be welcomed as I'm really stuck on this.
