Digital Mine Research and Practice Based on Mining and Metallurgy System Engineering

An-lin Shao

Frontiers of Engineering Management 2016, Volume 3, Issue 1,   Pages 67-73 doi: 10.15302/J-FEM-2016006

Abstract: Iron ore is necessarily basic raw material for industrialization and urbanization and related to the industrial distribution and development programming. The lean iron ore resource in our country is high-cost and low-efficiency, which cannot meet the demand of iron and steel industry, and even endanger the safety of industrial economy. Ansteel mining has created “grade decision-based multi-system integration” mode of mining and metallurgy system engineering and realized scale and efficient development of lean iron ore on basis of the construction of digital mines. Moreover, the “wisdom mines” was proposed and had led to the transformation and upgrading of iron developments.

Thermo-elastic extended meshfree method for fracture without crack tip enrichment

A. ASADPOUR

Frontiers of Structural and Civil Engineering 2015, Volume 9, Issue 4,   Pages 441-447 doi: 10.1007/s11709-015-0319-5

Abstract: This is the first manuscript presenting an extended meshfree method for thermo- elastic fracture which does not exploit a crack tip enrichment. The crack is modeled by partition of unity enrichment of the displacement and temperature field. Only a step function is employed that facilitates the implementation. To ensure that crack tip is at the correct position, a Lagrange multiplier field ahead of the crack tip is introduced along a line. The Lagrange multiplier nodal parameters are discretised with the available meshfree functions. Two benchmark examples illustrate the efficiency of the method.

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 5,   Pages 1180-1195 doi: 10.1007/s11709-020-0661-0

Abstract: Increasing the bending capacity of reinforced concrete (RC) elements is one of important topics in structure engineering. The goal of this study is to develop a transferred stress system (TSS) on longitudinal reinforcement bars for increasing the bending capacity of RC frames. The study is divided into two parts, i.e., experimental tests and nonlinear FE analysis. The experiments were carried out to determine the load-deflection curves and crack patterns of the ordinary and TSS fixed frame. The FE models were developed for simulating the fixed frames. The obtained load-deflection results and the observed cracks from the FE analysis and experimental tests are compared to evaluate the validation of the FE nonlinear models. Based on the validated FE models, the stress distribution on the ordinary and TSS bars were evaluated. We found the load carrying capacity and ductility of TSS fixed beam are 29.39% and 23.69% higher compared to those of the ordinary fixed beams. The crack expansion occurs on the ordinary fixed beam, although there are several crack openings at mid-span of the TSS fixed beam. The crack distribution was changed in the TSS fixed frame. The TSS fixed beam is proposed to employ in RC frame instead of ordinary RC beam for improving the performance of RC frame.
