A Micromechanics Damage Approach for Fatigue of Composite Materials

A new model for fatigue damage evolution of polymer matrix composites is presented. The model is based on a combination of an orthotropic damage model and an isotropic fatigue evolution model. The orthotropic damage model is used to predict the orthotropic damage evolution within a single cycle. The isotropic fatigue model is used to predict the magnitude of fatigue damage accumulated as a func...

A micromechanics approach for damage modeling of polymer matrix composites

A new model for damage evolution in polymer matrix composites is presented. The model is based on a combination of two constituent-level models an9 an interphase model. This approach reduces the number of empirical parameters ·since the two constituent level models are formulated for isotropic materials, namely fiber and matrix. Decomposition of the state variables down to the micro-scale is ac...

A micromechanics-based elastoplastic damage model for quasi-brittle rocks

This paper presents a micromechanics-based elastoplastic damage model for quasi-brittle rocks in compression stress state. The plastic strain is considered to be related to frictional sliding along microcracks and inherently coupled with damage evolution. By following a homogenization procedure, we first determine the free energy for the matrix-cracks system. The thermodynamic force associated ...

Cytoskeleton Micromechanics: A Continuum-Microscopic Approach

JENNIFER J. YOUNG: Cytoskeleton Micromechanics: A Continuum-Microscopic Approach (Under the direction of Sorin Mitran) Creating accurate, whole-cell scale models of the cytoskeleton is computationally challenging, due to the material’s highly heterogeneous microstructure. Continuumbased models, homogenization methods, and coarse grained models are common modeling approaches. These methods utili...

Unilateral Ptosis as Initial Manifestation of Acute Myeloid Leukemia

Abstract Background In Acute Myeloid Leukemia (AML), malignant clones of immature myeloid cells (primarily blasts) proliferate, replace bone marrow, circulate in blood and invade other tissues. The unique presentation of unilateral ptosis and unilateral eyelid swelling in AML has been reported during the present study. Case Report A 7-year-old girl was encountered with progressively increa...
