Comparison Between Numerical Analysis and Actual Results for a Pull-Out Test

Jakub GONTARZ, Jerzy PODGÓRSKI, Józef JONAK, Marek KALITA & Michał SIEGMUND
The paper describes a computer analysis of the pull-out test used to determine the force needed to pull out a fragment of rock and the shape of this broken fragment. The analyzed material is sandstone and porphyry. The analysis included a comparison of different methods of propagation of cracks in the Abaqus computer program using the Finite Element Method. The work also contains a description of laboratory tests and analytical considerations.

Approximate Estimation of Stability of Homogeneous Beam on Elastic Foundation

Iwona Małgorzata WSTAWSKA, Krzysztof MAGNUCKI & Piotr KĘDZIA
The paper deals with a proposition of obtaining an analytical solution for a beam on elastic foundation. The main objective of presented work was stability analysis of the axially compressed beam. The analytical model was proposed. Shape function for inhomogeneous properties of the foundation was assumed. The Galerkin method was used to calculate the values of critical forces. Main conditions have been defined. The critical loads as a function of geometric and mechanical properties of...

The Role of the Bone Strength on the Cyst Growth in the Mandible

Justyna MIODOWSKA, Jan BIELSKI & Magdalena KROMKA-SZYDEK
Intracystic fluid pressure is discussed as a potentially important factor influencing a bone cyst growth. This process can develop in the course of months. However, the exact mechanism remains speculative. In this paper, we use an established mathematical model to evaluate whether the presence of pressurized fluid in bone cavities may result in cyst growth. A continuous function of bone density rate vs. mechanical stimulus is used. The numerical model of the mandible with the...

Impact of Thermophoretic Transport of Al2O3 Nanoparticles on Viscoelastic Flow of Oil-Based Nanofluid over a Porous Exponentially Stretching Surface with Activation Energy

Christian John ETWIRE, Ibrahim Yakubu SEINI, Musah RABIU & Oluwole Daniel MAKINDE
The influence of thermophoretic transport of Al2O3 nanoparticles on heat and mass transfer in viscoelastic flow of oil-based nanofluid past porous exponentially stretching surface with activation energy has been examined. Similarity technique was employed to transform the governing partial differential equations into a coupled fourth-order ordinary differential equations which were reduced to a system of first-order ordinary differential equations and then solved numerically using the fourth-order Runge-Kutta algorithm with a shooting method. The results for...

Investigation of Monotonic and Cyclic Behavior of Soft Clay Using Direct Simple Shear Apparatus

Sutera BENCHANUKROM, Chitsirin LAILAK & Nirut KONKONG
The purpose of this research was to study the monotonic and cyclic simple shear mode behavior of Bangkok clay, using direct simple shear apparatus. The monotonic specimens were prepared in a saturated condition and were K0 consolidated before being undrained sheared. The specimens were sheared at the shear strain rate of 5% per hour until the shear strain reached 20%. The Stress History and Normalized Soil Engineering Properties (SHANSEP) method was applied to analyze the...
