Williams expansion-based approximation of the stress field in an Al 2024 body with a crack from optical measurements by S. Seitl, L. Malíková, J. Sobek, P. Frantík, P. Lopez-Crespo

“…Crack tip stress tensor components are expressed using the linear elastic fracture mechanics (LEFM) theory in this work, more precisely via its multi-parameter formulation, i.e. by Williams power series (WPS). Determination of coefficients of terms of this series is performed using a least squares-based regression technique known as over deterministic method (ODM) for which displacements data obtained experimentally via optical measurements are taken as inputs. …”

Modeling study of uniaxial compressive strength prediction from similar analog drilling test signals by Heqing LIU, Jiankang LIU, Jian HAO, Lijin ZHAO, Jianquan TANG

“…By varying the number of hidden layers, population and training function of GA−BP neural network, the factors affecting the prediction model and the results are discussed and analyzed to determine the optimal prediction model structure. The results indicate that there is a responding relationship between the vibration signal with drilling and the UCS of similar simulated materials, and the accuracy of the constructed prediction models are above 70%, and the research method of predicting the UCS with the perception of vibration signal with drilling has certain feasibility; The model results are optimal when trainlm is chosen for the training function, the hidden layer is 8, and the number of populations is 20,with coefficients of determination of 0.761 and 0.745 for the training set and the test set, respectively, the root-mean-square errors are 6.039 MPa and 4.254 MPa, and the mean absolute errors are 6.574 MPa and 4.716 MPa, respectively. …”
