Material database input issue in SW6
Thread Content
In SW6, I created new material data for use as heat exchange tubes. Why is the yield value at the design temperature 0 when making the call? Where does this problem lie? I need help from an expert, thank you! As shown in the figure

It’s been entered. Look at the first diagram: the yield limit marked in the red box is 205.
It’s not a reply to you – is that the yield strength at room temperature? You need to enter the yield limit at the specified temperature from the second row in the “Strength Data Type”!
Another set of temperatures at which yield occurs needs to be entered
At this temperature I set the yield limit; after increasing the yield strength, the set of allowable stress values corresponding to the originally entered temperature is no longer valid, and it is replaced by the yield limit value I just set. . How to solve it? Thank you
Got it. A separate set needs to be entered. It was called successfully. However, during the calculation, it is indicated that when calculating the external pressure, the temperature of the B curve for the material’s external pressure strain coefficient is out of range! How to solve this? Thank you
It’s still this interface: for material stress, the B-value curve still needs to be entered. Standards are available; don’t use standard curve graphs for the B curve, as measurements taken from such graphs may not be accurate. Instead, refer to tables, and you can calculate the values using interpolation methods
