Block geometry is commonly the most important feature determining the behaviour of a rock mass and directly controls the structural instability in underground openings or surface cuttings. Various methods are used to estimate block geometry and to perform a block survey, and these are standardly divided into empirical-based methods (e.g. spot mapping, linear mapping, areal mapping) and computer-based methods (e.g. laser scanning, image processing, digital image mapping). Empirical approaches are associated with effective features as well as with a number of errors; however, the latter can be covered by artificial intelligence (AI) techniques. The combination of image processing and areal mapping have led to geometric block estimation in two-dimensional (2D) and three-dimensional (3D) spaces; these approaches can be widely used in stability analysis, dimension stone extraction, excavations, open pit mining design and the delineation of blasting patterns for dimension stone extraction. Therefore, the application of an approach that allows both the modelling and production of rock blocks based on their actual status with qualified accuracy and speed are both worthwhile and necessary. In this study, to estimate the shape and block dimension utilized, we used the algorithm based on the AI image processing technique for rock mass structural detection and for rock block definition in 2D and 3D space obtained with the Mathematica software package. The algorithm, by categorizing the discontinuities in two groups (opened and closed), which represents the main and the secondary discontinuities, can identify the emplacement and shape of rock blocks.

Investigation of novel geometrical design concepts for damping treatments Çavuş, Bertuğhan; Özgen, Gökhan Osman; Department of Mechanical Engineering (2022-11) Surface damping treatment concepts are developed utilizing viscoelastic materials as a damping layer where it is applied to the main structure. The main aim for adding these materials is to increase cyclic deformation in the frequency region of interest, which increases dissipated energy from the main structure. Constrained layer damping treatment is the most common, where the viscoelastic layer is constrained by a stiff top layer. Recently, a spacer or standoff layer has been added between the base and con...
Numerical analysis of ablation process on a two dimensional external surface Aykan, Fatma Serap; Dursunkaya, Zafer; Department of Mechanical Engineering (2005) The thermal response analysis of an ablative material on a two dimensional external surface is performed. The method is applied to both rectangular and cylindrical coordinate systems, where rectangular coordinate system is used for comparison with results available in literature. The current study solves the decomposition of the material at high temperatures by using the nth order Arrhenius equation but excludes the removal of char from the surface due to mechanical erosion or phase change and considers tha...
Development of a shell finite element for large deformation analysis of laminated composites Yıldız, Tuba; Darendeliler, Haluk; Department of Mechanical Engineering (2008) The objective of the present work is to investigate the behavior of laminated fiber -reinforced polymer matrix composite shell structures under bending load with the help of a modified finite element computer code which was previously developed for the analysis of pseudo-layered single material shells. The laminates are assumed to be orthotropic and the formulation is adapted to first order shear deformation theory. The aim is to determine the large deformation characteristics numerically, and to predict th...
Case study: Planar kinematics of dragline for efficient machine control FRIMPONG, Samuel; Demirel, Nuray (American Society of Civil Engineers (ASCE), 2009-03-24) Overburden excavation is an integral component of the surface mine production chain. In large mines, the walking dragline is a dominant strip mining machine. Dragline performance depends on the operating speed, the bucket payload, and the machine availability, which could be negatively impacted by the actions taken to increase the machine productivity. In this study, the writers develop the kinematics and dynamic modeling of a dragline front-end assembly using the vector loop and simultaneous constraint met...
Numerical Study on CFRP Strengthening of Reinforced Concrete Frames with Masonry Infill Walls Akin, Emre; Ozcebe, Guney; Canbay, Erdem; Binici, Barış (American Society of Civil Engineers (ASCE), 2014-04-01) In the last decade, a new strengthening methodology has been developed for reinforced concrete (RC) frames with hollow clay tile (HCT) infill walls by means of diagonally applied carbon fiber-reinforced polymer (CFRP) fabrics. In the experimental part of a study conducted by the authors, this user-friendly methodology was experimentally investigated considering different aspect (height/width) ratios of the infill walls. In this study, first a numerical model of the FRP strengthened infill walls strengthened...
