Ebook :: Applied soil mechanics: with ABAQUS applications in PDF

A simplified approach to applying the Finite Element Method to geotechnical problems
Predicting soil behavior by constitutive equations that are based on experimental findings and embodied in numerical methods, such as the finite element method, is a significant aspect of soil mechanics. Engineers are able to solve a wide range of geotechnical engineering problems, especially inherently complex ones that resist traditional analysis. Applied Soil Mechanics with ABAQUS® Applications provides civil engineering students and practitioners with a simple, basic introduction to applying the finite element method to soil mechanics problems.
Accessible to someone with little background in soil mechanics and finite element analysis, Applied Soil Mechanics with ABAQUS® Applications explains the basic concepts of soil mechanics and then prepares the reader for solving geotechnical engineering problems using both traditional engineering solutions and the more versatile, finite element solutions.

Topics covered include:

  • Properties of Soil
  • Elasticity and Plasticity
  • Stresses in Soil
  • Consolidation
  • Shear Strength of Soil
  • Shallow Foundations
  • Lateral Earth Pressure and Retaining Walls
  • Piles and Pile Groups
  • Seepage
Taking a unique approach, the author describes the general soil mechanics for each topic, shows traditional applications of these principles with longhand solutions, and then presents finite element solutions for the same applications, comparing both. The book is prepared with ABAQUS® software applications to enable a range of readers to experiment firsthand with the principles described in the book (the software application files are available under "student resources" at www.wiley.com/college/helwany). By presenting both the traditional solutions alongside the FEM solutions, Applied Soil Mechanics with ABAQUS® Applications is an ideal introduction to traditional soil mechanics and a guide to alternative solutions and emergent methods.

Tunnelling in rock by drilling and blasting in PDF

Tunnelling in Rock by Drilling and Blasting presents the latest developments in the excavation of tunnels using the drilling and blasting method. Examples of work conducted throughout the world including the Indian sub-continent, Australia, and Sweden amongst others are discussed.
These tunnel projects serve to illustrate the challenges and importance of drilling accuracy, the effect of geology, methods of vibration prediction and control, and techniques for assessing tunnel performance in terms of overbreak and underbreak, advance and rock mass damage. A number of case studies demonstrate the ingenuity required to successfully excavate tunnels in demanding circumstances.
Finally, an overview is provided of the software tools and IT, and the explosives and initiation products used to implement tunnel blast designs.
Tunnelling in Rock by Drilling and Blasting is the outcome of the workshop, Tunnelling in Rock by Drilling and Blasting, hosted by the 10th International Symposium on Rock Fragmentation by Blasting (Fragblast 10, November 2010, New Delhi, India), and is essential reading for researchers and practitioners in tunnelling in rock by drilling and blasting.
