In this article, an intuitionistic interpretation of the new numerical implementation asymptotic homogenization for effective bending stiffness in-plane periodic plate structures is presented. Based on interpretation, a two-step method shear prediction their Reissner–Mindlin model developed. An equivalent displacement field linear curvature applied to unit cell in first step; second step, problem constructed and solved, obtained through energy equivalence. This can be easily implemented...

This article interprets the new implementation of an asymptotic homogenization method for effective bending stiffness heterogeneous beam structures with periodic microstructure along its axial direction in intuitionistic way. With this interpretation, authors then develop a evaluating shear their Timoshenko model. can be easily implemented numerically commercial software. Different kinds elements and modeling techniques available software applied to model unit cell. Several examples are...

Helically wound structures are widely used in practical engineering due to its excellent mechanical property, such as the steel rope, reinforced armor layer of marine flexible pipe/cables. The shear stiffness plays an important role exactly predicting response helically structure, especially for short structure. There has been no general methodology directly calculate effect this type structure because geometrical complexity. This paper introduces and modifies a novel implementation...

Based on the review of relevant researches logistics capability in domestic and oversea, this paper analyses theories chain store summarizes structure capability. It puts forward that is made up two aspects: static dynamic capability, develops measurement tool. The scale framework reliable valid, tested by sample collected from 48 enterprises.

Polycrystalline thin wire is an important geometric configuration in micro-electro-mechanical system and microelectronic devices. When the cross-sectional dimension comparable with grain size, mechanical properties of polycrystalline are different from those its bulk counterpart. In present paper, we use finite element analysis statistical concepts to numerically estimate effective modulus copper thin-wire configuration. As number grains cross-section increases, predicted approaches...

This work investigates asymptotic homogenization method (AHM) for axially graded beams that are mapped from periodic ones. The unit cell problems, the homogenized constitutive and governing equations first established theoretically. Then a novel FE formulation of problems effective stiffness, distinct beams, is derived resolved solid elements. Besides, to improve analysis efficiency, an updated concise acquired shell elements with proper handle in-plane rotational DOFs, MATLAB code presented...

Peer review plays an important role in research project selection at funding agencies. Given the practical challenge that even most experienced researcher may be unable to point out whole deficiencies a complex body of work, peer addresses this problem by introducing independent experts critically analyze and assess quality proposals. Recommending appropriate reviewers for proposals presents great agency especially when number are large. Reviewer recommendation involves several issues which...

This work investigates the two-scale design optimization of graded plates with variable-height parallelogram microstructures based on asymptotic homogenization. First, updated unit cell problems, an emphasis rotational degrees freedom, are proposed to evaluate shell-structured microstructures, so that a pointwise effective stiffness calculation can be efficiently conducted shell elements, which is otherwise computationally prohibitive solid elements. Then, framework seeking minimum...

Abstract Produced water (PW) is generated in a large amount worldwide and has complex compositions. PW treatment required to meet environmental regulations as well reuse recycling of PW. Meanwhile, plenty needed for slickwater fracturing applications during unconventional reservoir development. This study aims find effective ways treat formulate it into operations save fresh improve sustainability. A synthetic high salinity oily produced with overall more than 100,000 ppm was used. Searching...

Abstract Produced water (PW) is generated in a large amount worldwide and has complex compositions. Removing oil usually the main focus of treatment to meet environmental regulations as well reuse recycling PW. This study aims investigate cost-effective chemicals for high salinity PW with removal efficiency, short time low chemical dosage. High produced (HSPW) (LSPW) 102,290 mg/L 65,680 mg/L, respectively, were used this work. Three flocculants tested polymers different molecular weights...
