| Abstract: | According to the in-situ measurement of damage shape of
impacted object and the theory of direct back analysis, the magnitude of the
impact load and the dynamic tensile strength for laminar rock plank are
identified by taking the similitude-degree between the measured damage
shape and the
numerical simulated shape as the target function. The analysis method is
effective for some ancient architectures, especially
when the initial information and measurement data, are scare. |
