An Example of Microstructure with Multiple Scales [PDF]

, 1997
This paper studies a vectorial problem in the calculus of variations arising in the theory of martensitic microstructure. The functional has an integral representation where the integrand is a nonconvex function of the gradient with exactly four ...

Palaeoclimate of the Paleogene Dongying Formation in Bozhong Sag of Bohai Bay Basin

Petroleum Research, 2021
It was showed that the sedimentary environment of lacustrine basins is more susceptible to basin size than that of marine basins, leading to frequent changes in sedimentary environment and large differences in sediment supply and types.

Microstructure of compacted low-plasticity soils: the initial fabric and its evolution on stress and suction paths [PDF]

, 2023
Soils used in earthworks undergo different hydro-mechanical paths due to the compaction and construction process, the change in climatic conditions or the groundwater level oscillations.

Geochemical and gas bearing characteristics of the marine-continental transitional Longtan shales in southern Sichuan, China

Frontiers in Earth Science, 2023
Marine-continental transitional shale, as an important shale type, gains less attention than marine and continental shale, which restricts the exploration and development process of marine-continental transitional shale gas.

Differences in Pore-forming Efficiency among Organic Macerals and Its Restriction against Reservoir Quality: A Case Study Based on the Marine Shale Reservoir in the Longmaxi Formation, Southern Sichuan Basin, China

Lithosphere, 2021
Organic matter pores are of important significance in the shale formation system rich of organic matters. Although a lot of studies have discussed controlling factors of organic matter pores in the past, it still lacks a quantitative analysis on ...
