Microcracking and inelastic behavior of concrete

Sturman, G.M. / Shah, S.P. / Winter, G.

Inelastic behavior of concrete was studied by direct observations of internal microcracking; thin slices were made from strained specimens and internal cracks were examined by X-ray and microscope techniques; analytical and experimental studies showed that tensile stresses are present at mortar-aggregate interface because of volume changes of mortar and may be partly responsible for bond cracks in virgin concrete; bond cracks begin to propagate noticeably at applied compression stresses of one-quarter to one-third of ultimate strength; eccentrically loaded specimens were compared with concentrically loaded specimens for microcracking and stress-strain relation.
