%X The st ress- strain law of elastic body with microcracks is derived in which craick closing and crack surface friction are taken into consideration.An explicit expressionof flexibility tensor increment is found.The equivalent engineering moduli are given for thecases of two dimensional plane stress and plane strain.Numerical results show the noticeableinfluence of crack closing and crack surface friction on the stress-strain law of elastic bodywith micracracks.
