The Effect of Multiple Compliant Layers at the Fiber-Matrix Interface on Residual Thermal Stresses in Metal Matrix Composites
The large mismatch in thermoelastic properties of the fiber and matrix phases in advanced metal matrix composites, coupled with high consolidation temperatures, produces severe residual...

Composite Materials for Structures on Planetary Surfaces
Development of structures for planetary surface environments depends upon the use of the most appropriate materials. Advanced composite materials are apparently the best candidates for...

Comparison of Micromechanical Models for Elastic Properties
The effective elastic properties for unidirectional composites, as predicted by several analytical micromechanical models are compared for glass/epoxy and graphite/epoxy. A brief review...

Optimum Design of Laminated Composites
The increased demand for high strength, light weight materials that function successfully in high temperature environments has caused the effective development of laminated composites...

Combustion Synthesis of Advanced Materials
The combustion synthesis of ceramic-metal composites using an in-situ liquid infiltration technique is described. The effect of varying the reactants and their stoichiometry to provide...

Denver International Airport Fabric Roof Design
The design of Denver's Landside Terminal Complex for the new Denver International Airport, called for some far reaching vision coupled with imaginative building technologies. Because of...

Microbiologically Induced Corrosion
Researchers investigating a building whose columns bled a colorless liquid found that the building was under attack by microorganisms. A community of bacteria had contaminated the fireproofing...

Fiber: Good For the Concrete Diet?
Fiber reinforcement of concrete has many advantages, but after thirty years of research those benefits have most often been seen in a laboratory. Some materials, such as synthetic fibers,...

A Current Review of Experience with Asphaltic Concrete Impervious Membranes on the Upstream Slope of Earth and Rockfill Dams
At some sites where an earth or earth-rock dam is being considered, studies may indicate that the most economical and satisfactory dam would be obtained with a pervious embankment of soil...

Probabilistic Analysis of Post-Tensioned Steel Girder Bridges
External post-tensioning is used as a means of strengthening existing steel girder bridges. Since absolute safety of structures is impossible to attain due to uncertainty in load and resistance,...

A Unified Simulation Approach to Structural System Reliability Analysis
To determine accurate estimates for the system reliability of large complex structures requires considerable computation; unless the problem is assessed in an efficient manner the analysis...

Incorporating Corrosion in Reliability-Based Design of Anchored Bulkheads
Corrosion of steel is an important factor in the design of marine structures. A reliability analysis of anchored bulkheads showed that corrosion changes the critical failure mode from...

Experimental Study of the Transient Temperature Distributions in Concrete
A small scale, preliminary experimental effort to quantify the randomness of the thermal diffusivity of concrete has been undertaken. Two sets of cylinders have been instrumented with...

A Fatigue Reliability Model for Railway Bridges
A fatigue reliability model is described for safety evaluation of steel railway bridges. The model is a function of six independent random variables and can accommodate different types...

Low-Cycle Fatigue Prediction for Ramberg-Osgood Type Materials
The prediction of low-cycle fatigue crack growth is successfully made by an equation employing the J-integral range. This equation, originally proposed by Dowling and Begley, is analogous...

Stochastic Modeling of Short Fiber Reinforced Composites?A Review
Since the early 1960's, an extensive research and development has been carried out with fiber reinforced cements and concretes. Modeling of such heterogeneous material is still in the...

A Systems Reliability Approach to the Safety of Steel Connections
A methodology is presented to determine the probability of failure of steel connections using a systems approach. Results indicate that connection safety evaluations which do not use this...

Optimal Configuration for Fiber Reinforced Composites under Uncertainties of Material Properties and Loadings
