Approximate solutions and numerical analysis of a spring-mass running model

The present study concerns the development of a new iterative method applied to a numerical continuation procedure for parameterized scalar nonlinear equations. Combining both a modified Newton’s technique and a stationary-type numerical procedure, the proposed method is able to provide suitable approximate solutions associated with scalar nonlinear equations. A numerical analysis of predictive capabilities of this new iterative algorithm is addressed, assessed, and discussed on some specific examples.

Stress And Deformation

In this paper, the flexible modeling capabilities of ANSYS and the excellent nonlinear solving ability of ABAQUS were multiplied for simulating the deep 3D-excavation. The results illustrated that both advantages of two numerical analysis softwares were combined. The complex stresses and deformations of the deep 3D-excavation were exactly simulated. The approximate solutions show that this method could analyze the coupling effects between the soils and the walls of the 3D-excavation. It was a successful application of using advanced CAE technologies into geotechnical engineering.

Element Method

Shear strength characteristics of soil beneath the footing play a salient role on the stresses developed in the footing. In the design of foundation, it is imperative to analyse the stresses developed in it to prevent failures. Estimation of the influence of shear strength of underlying soil and flexural rigidity of footing on the shear force and bending moment developed in the foundation is necessary for effective determination of stress. Unlike conventional experimental methods, numerical analysis using Finite Element Method based geotechnical software like PLAXIS, FLAC, MIDAS etc. enables the analysis of foundations with complex stress characteristics. Finite Element Method (FEM) is a numerical analysis procedure that provides approximate solutions to various problems associated in the field of geotechnical engineering. This paper critically reviews the current literature on numerical methods to investigate the influence of shear strength of supporting soil on the structural forces developed in a footing. The relevance of the present approach to the concept of shear strength analysis is scrutinised by various numerical simulation analysis software.
