Document Type: Journal Paper


Hypothesis presented is that residual lateral compressive stresses may suppress ductility across notch and permit cleavage fracture to occur; theoretical explanation is given; tests made at Brown Univ on precompressed notched plates tested in tension (and on comparable cylinders) are used to check this principle; they provide substantiation within range of specimen geometry used.
