Surface Forms

Morphology

beat + someone's + brain + out

The violent sense is largely derivable from the parts—'beat' (to hit) + 'brain' (organ) + 'out' (completely/removed)—so a B1 learner who knows the words would likely infer severe physical assault or a hyperbolic threat. However the extended, non-literal sense meaning 'to work or study extremely hard' is not predictable from the constituents, making the expression only partially transparent.

Etymology

Beat someone's brains out uses a very strong image: beat (to hit) and brains (the mind in the head), as if someone were hit so hard their 'brains' were badly injured. That's why it can be a real threat, 'to hit someone violently', and by exaggeration it is also used to mean 'to work or think very hard'.
