surname, attested from late 12c., probably meaning bald head; cf. Wyclif Stye up, ballard, where Coverdale translates Come vp here thou balde heade [2 Kg.2:23-24, where God kills 42 children for making fun of Elijah's lack of hair.]
A slump is a form of mass wasting that occurs when a coherent mass of loosely consolidated materials or rock layers moves a short distance down a slope. Movement is characterized by sliding along a concave-upward or planar surface. Comments.
Crushing or compression failure occurs when short columns experience super heavy loads that exceed the material limits. Buckling failure occurs when tall, slender columns experience loads that cause them to buckle or shift outward to relieve stress. This is a geometric failure and will always be less than the compression failure limit.
