In pile foundation engineering, the pile side friction resistance is a very important aspect of bearing capacity of single pile, so the research of interaction between pile and soil is a key issue in pile foundation design.
In engineering applications, the experimental direct shear test, pullout tests or full scale in-situ test are utilized to research the pile-soil interface friction characteristics.
The engineering properties of soil are showed in Tab.1.

Introduction Cracking and fatigue are the most common and complicated failures that can cause damage to engineering structures due to mechanical and environmental loadings.
They have been nowadays employed as a standard tool to simulate fracture under static, dynamic and cyclic loading conditions in scientific and engineering communities.

A reliable prediction of crack initiation with its orientation and propagation path under mixed mode loading is desirable for life prediction of engineering components.
The last several decades have witnessed the great success of the finite element method, along with a tremendous increase of computer power, as a numerical simulation approach for applications across almost every engineering discipline [1].

This significance of the feature applying in practical engineering is that the rational use of aspheric optical system is smaller in size and less weight than the spherical system while the image quality is superior to the latter [1].
For this reason, aspheric surface has a wide range of applications in the civil, defense, and high-tech civilian areas.
In engineering applications, the minimum parameters in formula are available for their best match
Newton iteration method can be applied to solve the equations set in practical engineering.
