Constitutive model of metal rubber material considering plastic accumulation behavior by FENG Zhipeng, YANG Fang, FU Hailong, AI Shigang, WANG Yue, YUAN Liangyang

“…Building upon the memory recovery force model and based on the deformation mechanisms of metal rubber, a constitutive model is constructed considering three perspectives: work done to overcome elastic deformation, work done in plastic deformation, and energy dissipation through internal slip friction within the metal wire microstructure, aiming to precisely describe the energy dissipation process of metal rubber. …”

In situ rubidium–strontium geochronology of white mica in young metamafic and metasomatic rocks from Syros: testing the limits of laser-ablation triple-quadrupole inductively coupl... by J. Muñoz-Montecinos, A. Giuliani, A. Giuliani, S. Oesch, S. Volante, B. Peters, W. Behr

“…<p>The recent development of laser-ablation triple-quadrupole inductively coupled plasma mass spectrometry (LA-ICP-MS/MS) has revolutionized rubidium–strontium (Rb–Sr) mica dating, allowing us to obtain isotopic data within their microstructural context. While effective for old and felsic materials, this method presents challenges for young metamafic and metasomatic rocks due to limited radiogenic ingrowth associated with low <span class="inline-formula"><math xmlns="http://www.w3.org/1998/Math/MathML" id="M1" display="inline" overflow="scroll" dspmath="mathml"><mrow class="chem"><mi mathvariant="normal">Rb</mi><mo>/</mo><mi mathvariant="normal">Sr</mi></mrow></math><span><svg:svg xmlns:svg="http://www.w3.org/2000/svg" width="33pt" height="14pt" class="svg-formula" dspmath="mathimg" md5hash="c8cc8ceb6d3be37d07dd342c9dd7a9ce"><svg:image xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="gchron-6-585-2024-ie00001.svg" width="33pt" height="14pt" src="gchron-6-585-2024-ie00001.png"/></svg:svg></span></span> and young ages. …”
