Evolution of the Damping Ratio Considering Cyclic Confining Pressure Under Intermittent Cyclic Loading

Buildings
The damping ratio is essential to conducting dynamic analysis for underground engineering under traffic loading. Variations in the damping ratio are usually studied using cyclic triaxial tests with continuous cyclic loading; however, intermittent loading

Effect of circular holes on the ratchet limit and crack tip plastic strain range in a centre cracked plate [PDF]

, 2011
In this paper a centre cracked plate subjected to cyclic tensile loading and cyclic bending moment is considered. The effect of circular holes drilled in the region of the crack tip on the ratchet limit and crack tip plastic strain range is studied ...

Orthotropic cyclic stress-softening model for pure shear during repeated loading and unloading [PDF]

, 2014
We derive an orthotropic model to describe the cyclic stress softening of a carbon-filled rubber vulcanizate through multiple stress-strain cycles with increasing values of the maximum strain. We specialize the deformation to pure shear loading.

Mechanical Behavior and Damage Evolution for Granite Subjected to Cyclic Loading

Advances in Materials Science and Engineering, 2018
This paper focuses on the mechanical behavior and damage evolution of Huashan granite subjected to cyclic loading. Four levels of confining pressure (0, 15, 25, and 35 MPa) were applied during cyclic axial loading by using a Rock Test System (MTS815 ...

Experimental study on coupling effects of cyclic confining pressure and intermittent cyclic loading on deformation behavior of saturated soft clay

Yantu gongcheng xuebao
The deformation characteristics of soft clay under intermittent cyclic loading and cyclic confining pressure are studied by conducting two types of cyclic triaxial tests, i.e., continuous cyclic loading and intermittent cyclic loading triaxial tests, and

Cerebrospinal Fluid Liquid Biopsy Enables Targeted Therapy Without Tissue Diagnosis in Pediatric Low‐Grade Gliomas With BRAF V600E Mutation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT We present two pediatric cases of pediatric low‐grade gliomas (PLGG) with BRAF V600E mutations diagnosed and monitored using cerebrospinal fluid (CSF) liquid biopsy analyzed via digital droplet PCR (ddPCR), without tissue biopsy. Both patients were treated with dabrafenib and trametinib and monitored through clinical assessments, magnetic ...
