Physico-mathematical modeling and informational technologies| Резюме: | Analytical solution of the problem concerning the state of strain-stressed body with square notchand fractures on its bisectrices extension was obtained. Plastic zones development on fracturesextension under quasistatically increasing loading were investigated. Dependences of plastic zonelengths on load value for random relations between square side and fracture length were found.The effect of notch on plastic zones development was analyzed. The fractures with sufficientlylonger lengths located opposite to square side have little effect on plastic zones development. Butif the fractures of even considerably small lengths are present, plastic zones on their extensionsdevelop significantly in a different manner than zones beginning from notch tip without fractures nto neglect even the shortest fractures beginning from the notch tip. |
