Hello Everyone<\/p>\n

I\u00b4ve a doubt about stresses in assemblies. Specially at the corners and edges. For example I\u00b4ve done a simple assembly of a plate and a lug. I have defined the same boundary and load conditions for the following cases:<\/p>\n

1.-Assembly using bonded contact<\/p>\n

2.-Assembly using Share Topology<\/p>\n

I got the following results, where it is shown that in the corners for both cases there are high efforts, however it seems to me that these efforts are not correct to analyze whether the element fails or not. So I get the following questions:<\/p>\n

1.- Why are the efforts concentrated in the corners?
\n2.- Is there a way to eliminate these stresses, without modeling the weld? Because since this is the maximum point, the color scale identifies this value and can give a perception that some point of this design is failing.
\nI raise this because when you have too large assemblies, it is not efficient to model all the welds either.
\n3.- And in the case that welding is modeled, it would give me the perception that modeling a larger fillet would lead to having less stress in said area. Is this correct?
\n4.- Let’s imagine that this part is made of a single element (machined), without welding (or perhaps with a fillet that is too small). So, in this case it would not be necessary to model the weld, so when obtaining a stress greater than the yield stress in this area, will the part fail in that corner?<\/p>\n

<\/p>\n
