Failure Types of Draglines and Their Classification



Failure analysis of thin spray-on liner coated rock cores
Öztürk, Hasan (2017-09-01)
Thin spray-on liners (TSLs) are surface support materials used in mining and civil engineering projects since 1990s with a wide ranging area of application from bolt/mesh support replacement to pillar reinforcement systems. This study presents the investigation of pillar reinforcement capacity of the TSL coated andesite rock core by compression test to mimic pillar reinforcement effect. The uniaxial compressive strength (UCS), modulus of elasticity (E), and energy absorbance capacity of uncoated and 5 mm co...
Failure analysis of thick composites
Erdem, Melek Esra; Parnas, Kemal Levend; Department of Mechanical Engineering (2013)
A three-dimensional finite element model is constructed to predict the failure of a hybrid and thick laminate containing bolted joints. The results of the simulation are compared with test results. The simulation comprises two main challenging steps. Firstly, for a realistic model, a 3D model is established with geometric nonlinearities and contact is takeninto account. The laminated composite model is constructed by 3D layered elements. The effect of different number of elements through the thickness is in...
Failure analysis of tapered composite structures under tensile loading
Çelik, Ozan; Parnas, Kemal Levend; Department of Mechanical Engineering (2016)
A three dimensional finite element modeling approach is used to evaluate the effects of preliminary design variables on the performance of tapered composite laminates under tensile loading. Hashin failure criteria combined with a progressive failure algorithm is used for in-plane failure mechanisms and cohesive zone method is used for out-of-plane failures. The modeling approach is validated by a comparison with experimental results from literature. The validated model is used to examine various design vari...
Reliability-Based Risk Assessment of Rubble Mound Breakwaters Under Tsunami Attack
Ergin, Ayşen (2002-09-01)
In the reliability-based risk assessment, the second order reliability index (beta II) method and the Conditional Expectation Monte Carlo (CEMC) simulation were utilised in order to analyse the safety levels of Haydarpasa Port main breakwater, Sea of Marmara, Turkey. The failure probability was forecasted in the beta II method by approximating the Hudson performance surface with a second-degree polynomial having an equal curvature at the design point where the design and structural parameters were taken int...
Failure analysis of shear critical RC structural members
Sarıtaş, Afşin (2004-06-01)
This paper presents a beam finite element for the simulation of the monotonic and cyclic response of RC structural members under the interaction of flexure, axial force and shear. The proposed beam element follows the assumptions of the Timoshenko shear beam theory with a three-field Hu-Washizu variational formulation for the derivation of the element response. The nonlinear response of the element is obtained through section integration of nonlinear material response. A 3d plastic damage model for cyclic a...
