Unveiling the three-dimensional structure of galaxy clusters: resolving the discrepancy between X-ray and lensing masses

, 2010
[Abridged] We present the first determination of the intrinsic three-dimensional shapes and the physical parameters of both dark matter (DM) and intra-cluster medium (ICM) in a triaxial galaxy cluster.

A proposed generalized constitutive equation for nonlinear para-isotropic materials [PDF]

Finite element models of varying complexities were used to solve problems in solid mechanics. Particular emphasis was given to concrete which is nonisotropic at any level of deformation and is also nonlinear in terms of stress-strain ...

Stress transfer law in laboratory hydraulic fracturing experiments

Scientific Reports
During the true triaxial hydraulic fracturing experiments, the compression stress applied to the specimen surface cannot be transferred to the interior immediately, resulting in inconsistency with in-situ stress conditions.

Experimental study on granite and the determination of its true strain-rate effect

Latin American Journal of Solids and Structures
To accurately determine the true strain-rate effect of granite in split Hopkinson pressure bar (SHPB) tests, systematic experimental studies from quasi-static to dynamic loading on the same batch of granite samples is required.
