| Abstract | Finite element analysis of beams subjected to four-point asymmetric loading has been used to calculate the internal stress fields for different specimen and loading geometries. The shear stresses determined from these stress fields were significantly different from those calculated from simple beam theory. Laboratory experiments done on samples of columnar-grained fresh water ice showed that consistent values of shear strength were obtained provided specimen and loading geometries did not vary beyond a particular range. At -10 deg C an average shear strength of 600 kPa was determined. Special measures taken to reduce stress concentrations at the load application points resulted in an increase of the average shear strength to 1100 kPa. Based on this experience, a shear testing method for ice is proposed. |
