First Experiences with the Deformation Analysis of a Large Dam Combining Laserscanning and High-Accuracy Surveying
Civil Engineering Laserscanning Surveying Deformation Analysis
2015/11/13
Monitoring the static and dynamic behaviour of large dams has always been a topic of great importance, due to the impact these structures have on the whole landscape where they are built. Many instrum...
Deformation analysis of a bored tunnel by means of terrestrial laserscanning
Terrestrial laser scanning point cloud modeling tunnel deformation detection
2015/8/24
A procedure is developed, implemented and tested to detect deformations in a bored tunnel. Deformations can occur after construction of the tunnel is nished, i.e. between two measurement epochs, but a...
Deformation Analysis of Elastic-Plastic Two Layer Tubes Subject to Pressure: an Analytical Approach
Composite tubes Elastoplasticity strain hardening Tresca's criterion
2009/10/12
Analytical solutions are obtained for axisymmetric elastic-plastic deformations in tightly tted concentric tubes with xed ends subjected to either internal or external pressure. Tresca's yield crite...
Deformation Analysis of Woven Fabrics for Chair Seat Surface
Textile Yarn Weave structure Finite element method
2009/4/22
In today's office environment, the demand over a feeling of sitting is increasing by the spread of IT equipment. Because evaluation of human's feeling of sitting is difficult, this study proposes num...
