Progressive failure analysis of notched composite plate by utilizing macro mechanics approach

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 3,   Pages 623-642 doi: 10.1007/s11709-021-0726-8

Abstract: In this study, gradual and sudden reduction methods were combined to simulate a progressive failure inUsing the presented method, a progressive failure is simulated based on a linear softening law priorto a catastrophic failure, and thereafter, sudden reduction methods are employed for modeling a progressivefailure.The proposed method is intended to predict the first ply failure (FPF), LPF, and dominant failure modes

Finite element prediction on the response of non-uniformly arranged pile groups considering progressivefailure of pile-soil system

Qian-Qing ZHANG, Shan-Wei LIU, Ruo-Feng FENG, Jian-Gu QIAN, Chun-Yu CUI

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 4,   Pages 961-982 doi: 10.1007/s11709-020-0632-5

Abstract: A uniform arrangement of individual piles is commonly adopted in the conventional pile group foundation, and basin-shaped settlement is often observed in practice. Large differential settlement of pile groups will decrease the use-safety requirements of building, even cause the whole-building tilt or collapse. To reduce differential settlement among individual piles, non-uniformly arranged pile groups can be adopted. This paper presents a finite element analysis on the response of pile groups with different layouts of individual piles in pile groups. Using the user-defined subroutine FRIC as the secondary development platform, a softening model of skin friction and a hyperbolic model of end resistance are introduced into the contact pair calculation of ABAQUS software. As to the response analysis of a single pile, the reliability of the proposed secondary development method of ABAQUS software is verified using an iterative computer program. The reinforcing effects of individual piles is then analyzed using the present finite element analysis. Furthermore, the response of non-uniformly arranged pile groups, e.g., individual piles with variable length and individual piles with variable diameter, is analyzed using the proposed numerical analysis method. Some suggestions on the layout of individual piles are proposed to reduce differential settlement and make full use of the bearing capacity of individual piles in pile groups for practical purposes.
