<p>Plasticine is an artificial material made from solids such as gypsum, lime, mixed with petroleum jelly or micro wax and acid fat. The properties of plasticine are likely similar to natural clay influenced by oil content. information about mechanical still very rare, the study on it riquired must be conducted intensively. preliminary laboratory has been understand behaviour plasticines....

We demonstrate that stability criteria can be used to calculate the maximum angle of stability um of a granular medium composed of spherical particles in three dimensions and circular disks in two dimensions. The predicted angles are in good agreement with the experimental results. Furthermore, we determine the dependence of um on cohesive forces, applying the results to wet granular material b...

In this paper, a finite element modeling via ABAQUS/Explicit simulation on a novel fabrication miniature composite fuselage structure is presented. The fuselage structure is modeled as a continuum composite layup that consisted of a woven C-glass fiber/epoxy 200 g/m 2 composite laminated [908] with the orthotropic elastic material properties and adhesively bonded butt joint. The adhesively bond...

The theoretical treatment of the failure behaviour of bulk solids is often based on the simplifying assumption that the material acts as an isotropic continuum, regardless of the direction in which the stresses are acting. This article describes the results from measurements with both a standard Jenike shear tester and a biaxial tester which indicate that the yield behaviour of a cohesive solid...

Cohesive-frictional and rough powders are the subject of this study. The behavior under isotropic compression is examined for different material properties involving Coulomb friction, rolling-resistance and contact-adhesion. Under isotropic compression, the density continuously increases according to Bauers exponential law, see Ref. (Bauer 1999). However, at a certain pressure/density, the beha...

Although a thorough understanding of fatigue crack initiation is lacking, experiments have shown that the evolution of distinct dislocation distributions and surface roughness are key ingredients. In the present study we introduce a computational framework that ties together dislocation dynamics, the fields due to crystallographic surface steps and cohesive surfaces to model near-atomic separat...

Soil is naturally occurring material that is used for the construction of structures except the surface layers of pavements. This naturally occurring soil may not suit the design requirements of ongoing project. So, soil is to be prepared to meet the requirements called soil stabilization. Stabilization is the process of blending of different soils or mixing of additives to a soil to improve ch...

We study some generalized notions of cohesiveness which arise naturally in connection with eeective versions of Ram-sey's Theorem. An innnite set A of natural numbers is n{cohesive (respectively, n{r{cohesive) if A is almost homogeneous for every computably enumerable (respectively, computable) 2{coloring of the n{element sets of natural numbers. (Thus the 1{cohesive and 1{r{cohesive sets coinc...

Investigating the mechanical behaviour of silica bodies in oil palm empty fruit bunches (OPEFB) is important to improve the process of silica body removal. This study will assist in providing an understanding of the role of OPEFB as a bioresource material for the bioconversion process. The microstructure of silica bodies/protrusions on the OPEFB fibre surface was modelled using the finite eleme...
