Abstract

The distribution of circumferential strain of arterial cross-section is highest at intima and lowest at adventitia. However, the circumferential strain is theoretically severe at intima because there is strain concentration. The theoretical degree of the intimal strain cannot be explained in physiological condition even though artery is physiologically normal. Physiological adaptation may be undertaken to strain concentration. However, it is not clear, yet Residual strain of artery is eagerly studied. There is experimental evidence that residual strain exists in artery. When ring of artery is longitudinally cut, it is opened. Assumption is made that intimal strain concentration is reduced with the consideration of residual strain. This study experimentally attempts to quantify the effect of residual strain on circumferential strain which is determined under the assumption of zero strain with zero pressure.
