ABSTRACT
One image in the sequence of a trap door test (TD Test 5 Frame 2) is presented in Figure 2 in the form of a two and three dimensional stress distribution. An average cross section stress distribution of two
1 TACTILE SENSOR TECHNOLOGY
1.1 Overview
Grid based tactile sensor technology enables to measure stresses at a large number of points in close proximity, thus allowing for a realistic normal stress distribution. The sensors are made of two layers of polyester material and are about 0.3 mm thick. Consequently, the sensor can be viewed as non-intrusive with minimal effect of the measurement on the measured values. Initial applications of the technology for Geotechnical engineering were presented by Paikowsky & Hajduk (1997) and Paikowsky et. al. (2000).
