AbstractWe develop low-order triangular virtual elements for linear Kirchhoff–Love shells from an engineering point of view. Flat element geometry is considered, which enables a direct shell discretization with no need for a curvilinear coordinate system or predefined initial mapping.

AbstractThis study presents a model to accurately describe the nonlinear deformation pattern of rock creep damage process by incorporating energy principles. The model captures the accelerated creep deformation pattern by considering the relationship between time and creep parameters at each stage of rock creep. A nonlinear creep model based on energy conservation is developed by integrating the time-dependent creep parameters into the model.

In times of technology, machines have become part and parcel of our day-to-day life. The field of civil engineering has not been left untouched by that very fact. As a civil engineer, we are to design a stable and strong foundation for these machines. Before designing the foundation, a beforehand idea of the behaviour of foundation of machine provides a further pathway. This paper presents an analysis of machine foundation for Single Degree Of Freedom (S.D.O.F) system.

IntroductionMany geological hazards have been induced in geological materials, which are extremely inhomogeneous and composed of rock blocks with high strength, fine soils, and pores, called “soil-rock mixture” (S-RM) by scholars (Gao et al., 2018; Senthilkumar et al., 2018; Fu et al., 2020; Gao et al., 2021). Due to its very nature, S-RM usually exhibits very complex physical and mechanical behaviors (Xu et al., 2015; Zhang et al., 2015; Zhang Z. L. et al., 2016; Zhao and Liu, 2019).

AbstractRheological characterization of the rock surrounding the lower wall of Xianglushan No. 2 tunnel was made to investigate the degree of stability for assurance of the long-term stability of the rock. The creep parameters were extracted for the creep model for the rock mass in the fault zone. A micro-element was introduced to describe the accelerated creep deformation and a new accelerated creep model was established.
