To increase understanding of damage evolution in advanced composite material systems, a series of large deflection bending-compression experiments and model predictions have been performed for a woven glass-epoxy composite material system. Theoretical developments employing both small and large deformation models and computational studies are performed. Results (a) show that the Euler–Bernoulli...

Soft particle materials such as some pharmaceutical and food products are composed of particles that can undergo large deformations under low confining pressures without rupture. The rheological textural properties these thus governed by both rearrangements shape changes. For the simulation soft materials, we present a numerical technique based on material point method, allowing for elasto-plas...

One cellular function of intermediate filaments is to provide cells with compliance to small deformations while strengthening them when large stresses are applied. How IFs accomplish this mechanical role is revealed by recent studies of the elastic properties of single IF protein polymers and by viscoelastic characterization of the networks they form. IFs are unique among cytoskeletal filaments...

Abstract – Many materials of contemporary interest, such as gels, biological tissues and elastomers, are easily deformed but essentially incompressible. Traditional linear theory of elasticity implements incompressibility only to first order and thus permits some volume changes, which become problematically large even at very small strains. Using a mixed coordinate transformation originally due...

The shallow shells, characterized by deeections of the order of unity, small deformations and still smaller curvatures, have most thoroughly been studied in the literature. However, the momentum terms, due to which the shell diiers essentially from a membrane, are not negligible only for the shortwave length deformations, when the deeections are small, the deformations | of the order of unity a...

In part I of this work, we study adhesionless contact of a long rectangular elastic membrane with a rigid substrate. Our model is based on finite strain theory and is valid for arbitrarily large deformations. Both frictionless and no-slip contact conditions are considered. Exact closed form solutions are obtained for frictionless contact. For small contact, the differences between these two con...

in order to find a reference values of intra ocular pressure (lop) in the normal male and tamale dogs on the basis of sizes ages, a research project were conducted. for this purpose, during one year (1992-1993), the lop of total 360 dogs (180 males and 180 females. either large of small sizes) refered to the small animal teaching hospital of tehran university were measured by shiotz tomometer. ...
