MIXED METHODS OF EXPERIMENTAL AND NUMERICAL CALCULATION FOR STUDY OF CLENCHING POWER BETWEEN SLIP AND CASING

The experiments for anchor equipment and casing have been made by use of simulated equipment on ground. Strains on surface of casing are measured by using strain gauge. Strains of calculating element in each node are obtained on the basis of experimental data. In the numerical calculations finite element methods are used. Distributions of clenching power on each clenching tooth are obtained. Reliable data are provided for design of slip.
