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...
Stress Transfer Within Granular Geomaterials
Local stresses within granular materials are random variables whose variance depends on the size of the elementary surface considered. This paper shows that this 'mechanical scale effect'...
Random Aspect of the Stress Inside Granular Media
Micromechanics of granular media arose from the necessity of a better understanding of the relationship between the global behaviour of such materials and the physical phenomena which...

Constitutive Modeling for Material with Perfect Disordered Heterogeneity
Finite element analysis with large number of elements are performed to simulate perfect disordered heterogenous material. The probabilistic nature of the micromechanical behavior of the...
Probabilistic Assessment of Composite Structures
Formal procedures are described which are used to computationally simulate the probabilistic behavior of composite structures. The computational simulation starts with the uncertainties...
First Order Importance Sampling Method and its Variance Reduction
This paper proposes an Importance Sampling method for structural system reliability problems with linearized modal failure surfaces. It has the advantage of locating all samples in the...
Discrete Markov Process Approach to Fatigue Crack Growth
The discrete Markov approach considered herein is simple to implement and uses a two-dimensional stochastic model in conjunction with simulation to estimate model parameters. The possibility...
Random Response of Multicrystalline Structures
An approach to the probabilistic modelling and analysis of multicrystalline microfabricated beams is presented with application to micro-electro-mechanical systems (MEMS). Random, textured...
The General Theory of Quantitative Risk Assessment
From the many individual applications of quantitative risk assessment (QRA) that have been made in various fields, this paper abstracts and lifts out the concise, simple, and elegant cluster...
Moving Toward a Probability-Based Risk Analysis of the Benefits and Costs of Major Rehabilitation Projects
By the year 2010, 77% of the U.S. Army Corps of Engineer's projects will be over 40 years old. The Corps wants to allocate its scarce rehabilitation funds in a cost-effective manner. To...
Aversion to Epistemic Uncertainties in Rational Decision Making: Effects on Engineering Risk Management
When faced with epistemic uncertainties in a decision problem, subjective expected-utility theory (SEU) implies that the only relevant characteristic of these uncertainties is the mean...
Optimal Flood Warning Threshold: A Case Study in Connellsville, Pennsylvania
A methodology for selecting an optimal flood-warning threshold has been developed by Haimes et al. (1990). The probabilistic evaluation of a forecast system coupled with a stochastic dynamic...
A Probabilistic Regional Damage Estimation Model for Earthquake Occurrences
In this paper we present a model for estimating regional earthquake damage. The model utilizes the relational data base management system ORACLE and the geographic information system ARC/INFO...
Optimal Discretization of Random Fields for SFEM
A new method for discretization of random fields (representation in terms of random variables) is introduced based on the principle of optimal linear estimation theory. The method is more...
Reliability Analysis of Uncertain Systems Under Random Loadings
This study considers the reliability assessment of uncertain systems under random loadings. The fast integration method (Wen and Chen, 1987) in conjunction with a second order asymptotic...
