Geomechanics of Subsidence Due to Pumping of Groundwater
In this talk we describe a nonlinear theory for the classical problem of pumping of groundwater from a layered soil. The model soil system consists of three horizontal layers where a very...
Adaptive and Parallel Methods for Nonlinear Solid Mechanics
The solution of nonlinear problems, which are of importance to industry and in scientific computations, requires increasing degrees of resolution. This high degree of resolution can be...
Probabilistic Mechanics in Civil Engineering
This paper describes the background, purpose and activities associated with the ASCE Engineering Mechanics Division and its technical committees. This includes research in probabilistic,...
On the Influence of Seismically Induced Residual Forces on Bridge Abutment Design
The seismic design of bridge abutments depend on the anticipated movement of the abutment during the design earthquake. For seat-type abutments in which the backfill resistance can be...
Bayesian Reliability Updating of Existing Steel Girder Bridges
Bayesian statistics is used to update the reliability of existing composite steel girder bridges. A 60 ft. long simply supported superstructure is considered. The reliability for the ultimate...
Wind Cross-Spectrum Effects on Long-Span Bridges
This paper discusses current analysis for long span bridge response based on wind components. The authors summarize the development of techniques which take such components into account,...
Analytical Studies on the Seismic Response of Lead Rubber Base Isolated Bridges
Highlights of a study related to the response of base isolated bridges are presented. Four different analytical models are developed and used to evaluate the response of base isolated...
Wave Interaction with Fluid Mud in Rectangular Trench
Wave interaction with fluid mud in a rectangular trench is studied theoretically based on small-amplitude wave theory. The problem was formulated using the Voigt model for an viscoelastic...
Nonlinear Shoaling and Impact of Waves on Coastal Structures
A two-dimensional fully nonlinear potential flow model is used to calculate shoaling of solitary and enoidal waves over a sloping bottom and interaction with submerged or emerged coastal...
The Effect of Wave Grouping on the Characteristic Wave Height
Wave data from two field stations and from the laboratory tests have been analyzed. The groupiness factor is used to categorize the wave data for the discussion of the correlation between...
Micromechanics and Effective Properties of Elastic Particulate Composites
A new micromechanical framework is proposed to investigate the effective mechanical properties of elastic particulate multiphase composites. Exact ensemble-volume averaged field equations...
On Distributed Processing Applications in Finite Element Analysis
Computer architectures may be classified by the relationship between their instruction and data streams (SISD, SIMD, MISD, MIMD) and the locality of memory (shared, local). Distributed...
On the Role of Experimental Mechanics in Assessing the Performance of Concrete
The role of experimental mechanics in material characterization, design, construction, performance evaluation, repair, rehabilitation and finally destruction of concrete structures is...
Behaviour of Prestressed Concrete End Blocks
This paper briefly reports on a series of experiments carried out on strip-loaded prestressed concrete end blocks. The results show that corresponding design methods presently used in...
Energy Dissipation Characteristics of Rubber Cylinders
A simplified procedure for scaling the energy absorption characteristics of rubber cylinders during high speed impact is presented. Static and dynamic tests of scale model and full size...
Large Deformation Elastic Behavior of Low-Density Solid Foams
A strain energy function that describes the nonlinear elastic response of a three-dimensional open-cell foam is developed. A tetrahedral unit cell containing four half-struts that join...
Mechanical Characterization of the Soft Tissue in Horse Hooves
The laminar corium tissue of the equine distal digit (or horse hoof) has been tested uniaxial tension. The laminar corium tissue lies between the hoof wall and the underlying bone of the...
Nonlinear Behaviour of Schneebeli Packings
We present some experimental proofs of the influence of the disorder of contacts on the mechanical (non-local) behaviour of packings of cylinders. In particular, this disorder is responsible...
Use of Hierarchical Lattices for Predicting the Fluid or Stress Transfer in Concrete
Hierarchical lattices are used to study the influence of local disorder on the transfer of properties (stresses, strains, permeability) from the micro-scale to the macro-scale. They are...
