PSI is the term used for compressive stress(stress=F/Area). Tensile stress is under tension. Keep in mind I haven't cracked my engineering books in 12 years so no expressed or implied warranties here. The short of it is that the upper half of the branch joint(examining the vertical slice if you were to cut the branch flush from the trunk) will be under tension and the bottom half would be under compression. The whole "slice" is also under a shear force as well. This is from mechanics of materials(last engineering course I took before switching to Comp Sci). Just seeing those equations makes me miss the heck out of this stuff. What can I say. I'm a geek about anything I'm into.
