Abstract: Macroscopic elastic moduli governing the incremental deformations of lung parenchyma are calculated on the basis of a model for an individual lung element in the shape of a regular dodecahedron. ...

Abstract: Macroscopic elastic moduli governing the incremental deformation of pressurized lungs are calculated on the basis of a micromechanical study of an individual lung element (alveolus). The spongy ...

Abstract: A theoretical study is made of the implications of a Dugdale-Barenblatt model for fatigue crack growth under steady cyclic loading. Residual plastic stretches and the effects of crack closure ...

Abstract: On the basis of the nonlinear theory of membrane shells, a general finite-element procedure is developed for calculating the deformations in the stamping of sheet metal by arbitrarily shaped ...

Abstract: Formulas are presented for the axial buckling stresses of long circular cylindrical shells having localized or random axisymmetric imperfections. The results are asymptotic in character, applicable ...

Abstract: Elastic analysis of two parallel fibers in an infinite matrix subjected to longitudinal shear leads to some exact results for stress concentrations between the fibers. High shear stresses occur ...
