“…Recently to avoid the large mesh distortion a new computational tool remeshing technique [35][36][37][38][39] started to be applied in the conventional finite element analysis mainly for simulation of metal forming process. A few examples of application of remeshing to geotechnical problems have been also found in references [40][41][42], but direct applications to simulation of CPT have been not found.…”

Abstract. Numeric analysis of the large penetration of the cone in undrained soil using finite element method (FEM) is presented. Until now the computation procedures has not been developed to such an extent, that they could provide numerical solution of large cone penetration problem. In this paper for solving of the large cone penetration problem an updated Lagrangian formulation and finite element method are used. To overcome large distortion of the finite element geometry during cone penetration leading to illconditioning equations a remeshing technique is developed. The proposed remeshing technique enables the simulation of the penetration process until steady cone penetration is reached. The analysis of the cone penetration in undrained soil is provided. The comparison of current numerical results and other authors' results are presented.

“…A finite element procedure with automatic remeshing technique has been developed by Hamel et al (Hamel et al, 2000) using ABAQUS FE software to specifically simulate the clinching process. The resolution of the updated Lagrangian formulation is based on a static explicit approach.…”

“…Dieless clinching allows mechanical joining of magnesium materials with very short process times because components are heated in less than 3 s. Deformation simulations with DEFORM were used to study the impact that modified punch geometry parameters have on dieless-clinched connections of various combinations of materials and component thicknesses. (Hamel et al, 2000).…”

“…The need to join dissimilar [3], coated or hard to weld lightweight materials [4], led to rapid development of mechanical joining techniques such as clinched joints. To predict the mechanical behaviour of structures containing multiple clinched joints it is computationally infeasible to included detailed sub models of this type of joint [5]. Therefore it is important to investigate the possibility of an equivalent model for clinched joints.…”

Abstract. Clinching is a mechanical joining technique that involves severe local plastic deformation of two or more sheet metal parts using a punch and die. The local deformation results in a permanent mechanical interlock. It is widely applied as a reliable joining technique in automotive, heating, ventilation, air conditioning (HVAC) and general steel constructions and is still gaining interest. In FEA models of structures containing a large number of clinched joints, it is not computationally feasible to use detailed sub models of the joint. Therefore an equivalent model was proposed by Breda et al. to predict the force-displacement behaviour. This equivalent model was calibrated using a simple shear-lap and pull-out test. During the calibration step, some local effects due to the material properties are captured in the calibration parameters. This paper investigates the impact of the plastic material properties on this calibration method. The effect of strain hardening due to the bending process prior to pull-out testing, potential plastic anisotropy of the base material and their relation to the calibration parameters are investigated. This research has been validated with experimental results on mild deep drawing steel.
