The Deformation of Discontinuity in the DDA Method Jun LIU 1, a and Zhongkui LI2, b 1 Beijing municipal engineering research institute, Beijing, China 2 Department of hydraulic engineering, Tsinghua university, Beijing, China a liujun01@tsinghua.org.cn, blzk-dhh@tsinghua.edu.cn Keywords: DDA; The deformation of discontinuity; Displacement; Stress.
The actual engineering indicates that the deformation of control discontinuity is often greater than that of block, and can not be neglected; but the deformation of the smaller discontinuities may be neglected.
Introduction The jointed medium like rock masses will be encountered in many engineering problems, where discontinuities are dominant.

The Research on Management Maturity Evaluation Model of Petroleum Engineering Projects [J].
Any advanced management modes will not necessarily be able to bear fruit without staff quality as a support.
Therefore, the primary task of engineering project management is to mobilize the initiative of staff.
Thought must be advanced, thinking must be open, and mind must be clear to be of the excellent quality of thought.

Preface The 2nd international conference on Structural and Physical Aspects of Civil Engineering (SPACE-2013) was held in High Tatras, in November 27 - 29, 2013.
The conference was organised by Department of Structural Mechanics, Institute of Structural Engineering, Civil Engineering Faculty, Technical University of Košice, Slovakia in cooperation with Slovak Society of Mechanics, Slovak Academy of Science, Bratislava.
The main objective of the conference is to bring together researchers and engineers devoting their work to structural and physical problems in different areas of engineering applications on a common platform.
The conference objectives were the following: Static and dynamic analysis of structures Seismic and stability problems of structures Experimental analysis and diagnostics of structures Resistance, durability and reliability of structures Optimization of structures Numerical methods, simulations and mathematical applications Failure, damage and reconstructions of structures We strongly believe that SPACE-2013 will have a significant impact on the development of contemporary analytical, numerical and experimental methods in structural and physical problems, and will also create an opportunity for opening a forum for discussion and collaboration amongst the participants.
This special Issue of the Advanced Material Research Journal contains the selected papers presented in the topic of the conference on Structural and Physical Aspects of Civil Engineering.

Preface The volume contains selected peer-reviewed papers presented at the AMS-Workshop “Advances in Materials Sciences-2020”, which took place in the framework of the III International Conference on Advanced Technologies in Aerospace, Mechanical and Automation Engineering - MIST: Aerospace-III-2020 on November 20-21, 2020 (Krasnoyarsk, Russian Federation).
The Conference was jointly organised by the International and Russian Union of Scientific and Engineering Associations (Moscow, Russia), Krasnoyarsk Regional Union of Scientific and Engineering Associations, and Krasnoyarsk Science and Technology City Hall.
The Program Committee and Editorial Board included prominent professors and scientists from the Russian and International Union of Scientific and Engineering Associations, Russian Academy of Sciences, University of Maribor (Slovenia), Chinese-Ukrainian University (China), Ruhr University in Bochum (Germany), Siberian Federal University (Russia), Reshetnev Siberian State University of Science and Technology (Russia), Voronezh State Technical University (Russia) as well as specialists from Russian and foreign leading industrial enterprises.
