805006 ELASTIC-PLASTIC ANALYSIS OF GEOTECHNICAL PRO~X~MS BY MATHEMATICAL P R Y I N G Oloda, G; De Donato, 0 Int J N~n Anal Meth Gecmech, V3, N4, Oct-Dec
1979, I:r381-b,01 A numerical technique, based on a mathematical l~OgrAmm~ug algorithm, is presented fer the solution of geotee~nical problems where elasticplastic material behaviour is considered. The loading process is subdivided into a series of steps applied to a finite element mesh with geometry amd material l~operties constant along each step, but with possible chamges between subsequent steps. Some typical geotechnlcal problems are amalysed by means of the proposed algorithm am~ a comparison is made between the available in situ measurements and the ~ i c a l results.

A modelling of the effective anisOtropic elasticity tensor is presented for elastic rocks permea. ted by a rather dilute concentration of stressinduced dry and saturated flat cracks. An exact analytical expression of the 3 wave velocities and attemnations in a ~ oblique direction is obtained fer the various crack distributions considered. A comparison is made with s~herical cavities. This study is lir~ked to ~he mechanical behaviour of cracked rocks under varying stress ard also has relevance in a seismological context to the detection of cracke~ zones and may be useful in the investigation of earthquake dilatancy.
