[Marvel Cinematic Universe] When Cap's shield is thrown, why does its edge sometimes (elastically) bounce off things, while other times it (inelastically) gets lodged inside things? I've watched numerous movies carefully but I can't find any pattern or governing principle. Thanks!

Its all about edge alignment. If the edge is oriented such the it strikes on the surface of the shield's 'dome' then it bounces elastically. If it strikes on the edge in a scooping motion it cuts. Cap is just so proficient with it that he can control which alignment will strike the desired target.
