does anyone know the value for the yeild strength of ABS as it would be used in SW? I can get a value from MatWeb, but I get pretty confused trying to associate this with the values used be SW and Cosmos Express - any help would be much appreciated!
The critical question is, what are you trying to model? If you are designing a one-time snap and it doesn't matter if the part yields slightly you will use a different value than if you are designing a part that is expected to flex thousands of times. Is it a momentary stress or is it a constant load on a part expected to be in service for 10 years? Is it an impact load? Is the part stressed at room temperature or at some high or low temperature? Is it a tensile stress, a compressive stress, a flexural stress? How is the part manufactured? If it is injection molded, is there a knit line in a highly stressed area? Which grade of ABS? What are the consequences of a failure? The answers to the above question would probably change the value I would use for my failure criteria by a factor of 10 or more.
