RISProbabilistic Model for Polycrystalline Microstructures with Application to Intergranular Fracture
Publisher: American Society of Civil Engineers
Abstract: A two part probabilistic model for polycrystalline microstructures is described. The model utilizes a Poisson–Voronoi tessellation for the grain geometry and a vector random field model for the crystallographic orientation. ...
Random Composites Characterization Using a Classifier Model
Publisher: American Society of Civil Engineers
Abstract: A new method is introduced for characterizing and analyzing materials with random heterogeneous microstructure. The method begins with classifiers which process information from high-fidelity analyses of small-sized simulated ...
Response of Open Cell Aluminum Foams to Fully Reversed Cyclic Loading
Publisher: American Society of Civil Engineers
Abstract: The response of metal foams to fully reversed cyclic loading has been investigated much less than the response to tension-tension and compression-compression cyclic loads. This paper describes tests of open cell aluminum ...
Loads of Infrequent Construction-Related Activities on Low-Slope Roofs
Publisher: American Society of Civil Engineers
Abstract: AbstractCauses of roof live loading are generally poorly described in codes and load standards,
which typically only state that these loads occur during “maintenance-repair” or other
similar activities. However, it remains ...
Probabilistic Models for Wind Turbine and Wind Farm Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A Markov model for the performance of wind turbines is developed that accounts for component reliability and the effect of wind speed and turbine capacity on component reliability. The model ...
Modeling the Effect of Void Shapes on the Compressive Behavior of Parallel-Strand Lumber

Development of Laminated Bamboo Lumber: Review of Processing, Performance, and Economical Considerations
Publisher: American Society of Civil Engineers
Abstract: As focus is drawn toward more sustainable construction practices, use of bamboo as a structural building material is growing as a topic of interest. It is highly renewable, has low-embodied energy, and has the highest ...
Characterization and Probabilistic Modeling of the Mesostructure of Parallel Strand Lumber
Publisher: American Society of Civil Engineers
Abstract: Parallel strand lumber (PSL) is a composite made of oriented wood strands that have been glued and compressed together. Its market share in the residential construction industry is considerable, being used primarily as ...
Variability of the Mechanical Properties of Wrought Iron from Historic American Truss Bridges
Publisher: American Society of Civil Engineers
Abstract: The mechanical properties of wrought iron from multiple elements of six late 19th-century truss bridges is evaluated by a program of destructive and nondestructive testing, including hardness testing and tension tests to ...
Measurement and Stochastic Computational Modeling of the Elastic Properties of Parallel Strand Lumber
Publisher: American Society of Civil Engineers
Abstract: This paper describes a model for the spatial variation of the elastic modulus of parallel strand lumber (PSL) that is based on bending experiments and also describes a validated stochastic computational model that incorporates ...
