In this research a comprehensive finite element program was developed in order to carry out an elasto perfectly plastic analysis of geogrid reinforcement of a model pavement. Qualitative agreement is seen between the numerical results and experiment. The results indicate the influence of geogrid in reduction of vertical deformation of pavements. It is also seen that for strong subgrade, the opt...

Introduction Lateral tape motion (LTM) is the time-dependent displacement of magnetic tape perpendicular to the tape transport direction. Lateral tape motion may cause track misregistration between the read/write head and a previously written track, thereby limiting the recording density that can be achieved [1]. Currently, the track density of typical magnetic tape drives is approximately 40 t...
