ABSTRACT
The development and extension of large cities creates a need of multiple shallow tunnels in the soft ground of built areas. Excavating a tunnel generates ground displacements and deformations which can affect existing buildings and services in urban sites and can lead to unacceptable damages. Prediction of the ground settlement caused by the tunnel excavation has been a major engineering challenge.
A numerical simulation using finite element method was implemented in the aim of ...

Penelitian ini bertujuan untuk mengidentifikasi program SPH yang mampu memodelkan fenomena keruntuhan lereng dengan 2 pendekatan SPH yang berbeda dibandingkan untuk mengamati bagaimana perilaku partikel saat mensimulasikan keruntuhan lereng. Program SPH Drucker-Prager dipilih karena mencakup parameter tanah yang diperlukan untuk memodelkan keruntuhan lereng. Program SPH Drucker-Prager dimodifikasi dengan menambahkan efek gravitasi pada partikel yang meningkatkan perilaku partikel. Tekanan Isotropik, Densitas dan Viskositas Semu dalam Program SPH yang dimodifikasi dianalisis untuk memeriksa apakah sesuai dengan kondisi ...

This book summarizes the results of years of research on the problem of strength and fracture of polymers and elastomers. It sets out the modern approach to the strength theory from the standpoint of fractals, the kinetic and thermodynamic theories as well as the meso-mechanic destruction. The dimension reduction method is applied to model the friction processes in elastomers subjected to the complex dynamic loading. Finally, it analyses a relation between the fracture mechanism and ...
