Analysis and Testing of Graphite/Epoxy Concrete Bridge Girders Under Static Loading
  B. M. Kavlicoglu, F. Gordaninejad, M. Saiidi, Y. Jiang
  "An innovative graphite/epoxy-concrete (G/E-C) cross-section was developed and tested under two-point static loading. Finite element analysis and theoretical modeling of the cross-section was performed. The cross-section was a box girder with an outer G/E U-beam and inner G/E box beam with concrete webs and flange in between. Shear connection between G/E box beam and concrete slab was provided by a two-part structural epoxy resin. Additional shear connection was provided by steel stirrups located at 254 mm (10 in.) spacing along longitudinal axis of the test specimen. It was observed that, steel stirrups contributed the load carrying capacity after initiation of slippage between G/E beams and concrete. Moreover, a series of bond strength tests were performed to examine the behavior of structural epoxy resin for connection between G/E and concrete. Six G/E strips were subjected to tensile tests to evaluate the longitudinal and transverse elastic moduli of the laminate. Using the proper material properties and assumptions, it was possible to demonstrate the behavior of the section under static loads theoretically and in finite element analysis."

Analytical Modeling Of Glued Laminated Girder Bridges Using ANSYS
  Anil Kurian
  "This paper aims at developing a finite element model of glued laminated girder bridges that can predict accurately the analytical behavior of the bridges. Two models have been developed to study the characteristics of this type of bridge. Two case studies have been considered to validate the accuracy of the models. The first case study is a long span single-lane bridge, the Tuscaloosa Bridge, in Alabama. The second case study is a medium span two-lane bridge, the Cow Gu lch Bridge, in Montana. The models show good correlation with the experimental data and hence, the models can be used to find the maximum deflections in the bridge."

Anisotropic Plasticity and Failure Prediction in Wood Composites
  David M. Moses, Helmut G.L. Prion
  "Two case studies are summarized using anisotropic plasticity and the Weibull weakest link failure model to predict the behavior of wood and wood composites. The linear elastic orthotropic model normally used for wood is shown to be insufficient for the prediction of ultimate strength in wood. Non-linear, non-recoverable behavior in compression in each of the orthogonal material directions is of particular interest in cases where localized crushing governs the load-displacement behavior of wood."

"The anisotropic plasticity option in ANSYS was used to predict yielding and post-yield behavior for the wood composite used in this study because yield stresses in orthogonal directions were found to be in the ratio of 1:1.2:5. A user-programmable Fortran subroutine was developed for ANSYS to carry out the failure analysis (and to calculate the volume integration of the stresses) at each load-step in post-processing. The model was verified using two cases: I) the ASTM D143 shear block test, and II) bolted connections."

Dynamic FEA and Simulation for A Series of Blast-Resist-door
  Lu Xinzheng and Jiang Jianjing
  "A series of blast-resist-door were used widely. In order to know the behavior of the doors under blast load and verify the safety of the doors, dynamic finite element analysis and simulation are carried out with advanced FEA software, ANSYS/LS-DYNA and SAP. Contact surfaces are introduced to simulate the relation between the door leaf and doorframe, as well as the relation between the door hinges and bearings. Altogether 24 different load cases are analyzed to simulate various load conditions."

Dynamic Pile Testing and Finite Element Calculations for the Bearing Capacity of a Quay Wall Foundation
  F. Kirsch, B. Pla▀mann, T. Huch, W. Rodatz
  "In April 1999 the construction of a new quay wall in the port of Hamburg started. In a first stage two new berths with an overall length of 1400 m will be built. In order to proof the bearing capacity of the foundation dynamic pile testing is performed to a great extent. To date more than thirty different piles were tested by the Institute for Foundation Engineering and Soil Mechanics of the Technical University of Braunschweig. In order to check for possible set-up effects redriven tests were performed. For comparison reasons static load tests were also carried out, one of which was done with an instrumented pile to allow skin friction and end bearing to be evaluated separately. The CAPWAP results proofed to be very helpful especially in those cases where the testing situation differed from the later service condition. Special questions called for detailed finite element analysis of the load-settlement behaviour of single piles in certain construction stages."
Although ANSYS is not explicitly mentioned, F. Kirsch also used ANSYS in two related papers, Stability of the vault developing over Soilcrete bodies and Ground Improvement and Its Numerical Analysis.

Effects of Nonlinear Geometric and Material Properties on the Seismic Response of Fluid/Tank Systems
  He Liu, Daniel H. Schubert
  "To explore the effects large deformation and nonlinear material properties have on the seismic response of fluid/tank systems, the computer program ANSYS was selected to develop a Finite Element Analysis (FEA) model of a ground level, cylindrical steel shell and roof tank structure with contained fluid under seismic load. The ANSYS program was selected for its ability to include shell and structural steel elements, contained fluid elements, fluid-structure interactions, material and geometric nonlinearities, and contact type elements. For purposes of this study, analysis results from a linear elastic, small deformation fixed base model are compared with an elasto-plastic material property model with large deformation assumptions. Results show the significant difference in results based on the assumptions used and indicate that current design code based values may not be conservative in resultant loading calculations."

Element for Modelling of Interaction Between Foundations and Bedrock in ANSYS Software
  Radim Cajka, Ondrej VÝta
  "Ansys provides standard solutions to contact tasks. It is a high-performing computing tool that offers several modifications, making it possible to create a new element and adjust the calculation to individual requirements. When dealing with specific problems relating to the contact between the foundation and the foundation soil, it is possible to create an element that will take into account the behaviour of a soil layer under the foundation exposed to shear. The shearing load can be caused by undermining, concrete creep, or concrete shrinkage."

Non-Linear Problems Of Steel Civil Engineering Structures
  Milan Vasek
  "The civil engineering structures are today designed with respect to the limit state of serviceability and limit states of the strength and stability. The design of more efficient and light structures leads to the nonlinear analysis of deflections and stresses. Some parts of structure could reach the yield point under the design load. Some parts of structure could lose their local stability. These complex problems of a different nature are possible to solve by FEM methods."
