A torsion test for the study of the large deformation recovery of shape memory polymers [PDF]

open access: yes, 2011
A torsion device was designed and built for testing the shape fixity and shape recovery of shape memory polymers at large deformation. A simple thermal chamber was used to regulate the thermal environment during testing and a CCD camera was used for ...

Large Deformation Characteristics of Surrounding Rock and Support Technology of Shallow-Buried Soft Rock Roadway: A Case Study

open access: yesApplied Sciences, 2022
The coal resources in the coal-rich area of western China are mostly located in the late diagenetic Cretaceous and Jurassic strata. In this paper, a study on the support of soft rock roadways was carried out in the background of the soft rock track ...

Understanding large plastic deformation of SiC nanowires at room temperature [PDF]

open access: yes, 2011
Tensile behaviors of SiC [111] nanowires with various possible microstructures have been investigated by molecular-dynamics simulations. The results show that the large plastic deformation in these nanowires is induced by the anti-parallel sliding of 3C ...

Curvature Correction of a Notched Continuum Robot Based on a Static Model Considering Large Deformation and Friction Effect

open access: yesMachines, 2022
Continuum robots are often used as wrist joints in medical robots because of their high dexterity and flexibility. Especially, the notched continuum robot (NCR) is used in the miniaturized wristed surgical robot.

Analytical Study of a Circular Thin Plate Contacting with an Elastic Sphere

open access: yesApplied Sciences, 2022
The problem that is addressed here is that of a circular thin plate clamped peripherally with frictionless contact to an elastic sphere. A complete and effective solution to this problem is developed to describe the relationship between the contact force

The Effect of Particle Shape on the Compaction of Realistic Non-Spherical Particles—A Multi-Contact DEM Study

open access: yesPharmaceutics, 2023
The purpose of this study was to investigate the deformation behavior of non-spherical particles during high-load compaction using the multi-contact discrete element method (MC-DEM). To account for non-spherical particles, the bonded multi-sphere method (

Recent Crustal Deformation in West-Central South America [PDF]

open access: yes, 2003
I use interferometric synthetic aperture radar (InSAR) to create maps of crustal deformation along the coast and within the volcanic arc of central South America. I image deformation associated with six subduction zone earthquakes, four volcanic centers,
