TL;DR: In this paper, a brief overview of the buckling of composite laminates made of continuous, parallel fibers is presented, and the effects of initial imperfections and postbuckling behavior are also described.
Abstract: A brief overview is presented of considerations involved in the buckling of composite plates made of laminae having continuous, parallel fibers. Such plates are governed by orthotropic or anisotropic plate buckling theory for laminates which are symmetrically stacked with respect to the plate midplane. Unsymmetric laminates require a more complicated theory with bending-stretching coupling. Additional complicating factors are considered, including: interior holes, shear deformation, sandwich construction involving other materials, local effects, nonlinear stress-strain relationships, hygrothermal effects, and external stiffeners. Postbuckling behavior and the effects of initial imperfections are also described. Some representative results from the extensive literature (352 references) are included to aid in describing the various effects.

TL;DR: In this article, a survey of structural approaches to the problem of rock bursting in coal mines is presented, leading to simple approximate conditions for the risk of initiating rock bursts, or for its efficiency.
Abstract: Since long ago rock bursting has belonged to the most hazardous of events causing damage to material and loss of human life in underground cavities. Nevertheless, attempts to understand the physical principles of rock bursting from the point of view of the mechanical and material sciences seem to be of fairly recent origin. The following article deals especially with rock bursting in coal mines. After a general introduction, approaches based on a specific property of the excavated material called “proneness-to-bursting” are reviewed. This is followed by a survey of structural approaches to the problem. Finally, an elementary structural model is presented, leading to simple approximate conditions for the risk of initiating rock bursts, or for its efficiency.

TL;DR: The United Kingdom has made substantial contributions during the last few years to the field of ice mechanics and ice forces on offshore structures as discussed by the authors, and significant advances have been made in theoretical understanding.
Abstract: The United Kingdom has made substantial contributions during the last few years to the field of ice mechanics and ice forces on offshore structures. Experimental studies have been carried out in the field and in the laboratory, and significant advances have been made in theoretical understanding. This paper summarizes the most recent contributions.
TL;DR: A summary of the major developments is given in this article, where a lot of ice mechanics research has been devoted to arctic offshore applications, including sea ice monitoring and statistics, ice forecasting, testing of mechanical properties, ship and icebreaker model testing and full-scale trials, ice resistant aids-to-navigation, and theoretical modelling and numerical simulations.
Abstract: In Finland, 110 years of winter navigation has been a natural initiator of ice mechanics research. It has brought with it sea ice monitoring and statistics, ice forecasting, the testing of mechanical properties, ship and icebreaker model testing and full-scale trials, ice resistant aids-to-navigation, and theoretical modelling and numerical simulations. Lately, a lot of ice mechanics research has been devoted to arctic offshore applications. A summary of the major developments is given in this paper.
