A probabilistic model for fatigue damage accumulation in composite laminates
A stochastic model for the accumulation of fatigue damage in composite laminates is proposed. The model considers the accumulation of fatigue damage as an evolutionary stochastic process and attempts to predict the ...
Selected mechanical problems in load- and depth-sensing indentation testing
Indentation techniques are used extensively in mechanical property testing. In this dissertation, selected mechanical problems in load and depth sensing indentation testing are presented. One commonly used technique for ...
Application of Markov chains to the critical element model for determining the fatigue life of composites
A stochastic model for predicting the lifetime of composite laminates subjected to multiaxial fatigue loading is proposed. The model is based on the application of Markov chains to the well known "critical element" model ...
Micromechanical modeling of elastic-plastic porous materials using finite element analysis
Elastic-plastic behavior of porous materials is analyzed using a hollow sphere micromodel and the NIKE2D finite element program. Surface average responses are computed for several displacement controlled homogeneous loadings. ...
Interfacial dynamics of liquid droplets and thermophysical property measurement
The interfacial dynamics of a viscous droplet immersed in a viscous medium are considered. The characteristic equation is derived using a normal-mode analysis, and solved for arbitrary, finite fluid properties. The cylinder ...
