In posttensioned concrete members, the high local stress under the anchorage causes transverse tensile stress. Therefore, it is very important to predict the bursting force to determine appropriate reinforcement details. In the present work, the existing equations of the bursting force for the anchorage zone were evaluated and an equation for the bursting force based on finite element analysis was proposed to improve the model’s accuracy. Parametric analysis was performed considering the anchorage shape, tendon angle, and eccentric distance. The analytical results indicate that the existing equations underestimate or overestimate the bursting force. The proposed equation is able to predict the bursting force reasonably well for an anchorage zone with rectangular bearing plate, cavity, and eccentric distance.

Torque Transmission

The torque shaft of shearer cutting part plays a dual-function of torque transmission and overload protection when the Shearer is working. Therefore it is necessary to study the reliability of the torque shaft. First, the parameterized torque shaft model was built on Inventor and simple parametric analysis of the torque shaft was done by its finite element analysis module. The unloading groove depth 5.079mm met the overload protection requirements. Then the model was imported into professional finite element analysis software Algor to verify the results. Linear statics analysis in Algor showed that when unloading groove depth valued 5.479mm the torque shaft would be broken once the shearer overload. The results of the analysis were reliable as no data was lost during the model interaction between Inventor and Algor.

Set Up

The design of pipeline protection with rock armour berms has been traditionally based on model testing because there has been no closed-form analytical solution available to resolve the complex interaction between the anchor, anchor chain, seabed soil and rock armour. Compared to the costly physical model test, a numerical procedure properly set up allows effective and extensive study on various rock berm configurations. It is expected that better optimized pipeline rock armour protection berm can be designed to offer appreciable savings on project cost. The authors have developed a Finite Element Analysis (FEA) based procedure which can predict the clearance between the anchor fluke tip and pipeline as well as the pushing force on the pipeline during anchor dragging. Both the clearance and pushing force can be used to assess the potential anchor damage to a pipeline with rock backfill protection. The FEA results have been successfully validated against results obtained from physical model tests. A series of numerical tests are performed considering the variations in the trench profile, the armour rock shape, rock particle size and grading properties etc. The protection mechanism of the rock armour berm, with regard to the above factors, is discussed to provide a better understanding for the significance of each parameter in the protection design. Guidelines in achieving an optimized rock berm protection design are also given.

Abstract In this paper, quasi-static out-of-plane compression behaviors of Miura-ori patterned sheets were investigated numerically by using finite element analysis (FEA). The simulation results show a reasonable agreement with the experimental results. In addition, the parametric analysis of the Miura-ori patterned sheets with different cell wall thicknesses, side lengths, dihedral angles and sector angles were carried out using FEA method. The influences of different parameters on the peak force and mean force were determined.

Generation Problem

A detailed nonlinear three-dimensional (3-D) finite element analysis (FEA) was performed in Phase I on a NEMO (naval experimental manned observatory) type HBOI (Harbor Branch Oceanographic Institution) spherical acrylic submersible in order to overcome the crack generation problem at its interfaces. An FEA has been carried out to develop a new design guideline, by reducing the higher stresses and relative displacements at the interfaces, which are believed to be two of the main reasons for crack generation at these areas. Variation of the stiffness between dissimilar materials at the interface, lower nylon gasket thickness, overdesigned aluminum hatch and bottom penetrator plug, attachment of the retainer ring with hatch ring, close placement of the rubber padding to the interface between the acrylic sphere, and the retainer ring are found to be the various causes for higher stresses within the acrylic sphere at the nylon gasket/acrylic interface. Based on the new design guidelines, in Phase II, a new spherical acrylic submersible was fabricated and tested. This design resulted in significant improvements by reducing the peak stresses and relative displacements at the gasket/acrylic interface areas. This improvement in design is expected to significantly extend the crack-free cyclic fatigue life of the acrylic submersible at 3000 ft (914 m) ocean depth.
