Streszczenie:
The Continuum Damage Mechanics is a branch of applied mechanics that used to predict the initiation of cracks in metal forming process. In this article, damage definition and ductile damage model are explained, and also ductile damage model is applied to predict initiation of fracture in gas metal forming process with ABAQUS/EXPLICIT simulation. In this method instead of punch, the force is applied by air pressure. In this study, first the ductile damage criterion and its relations are taken into account and, subsequently, the process of gas-aid formation process is put into consideration and

The processes in the metal sample of a supply pipeline realized under drop-weight tests (DWT, or DWTT according to ASTM) are studied. DWT is a proof test of the pipeline metal that should ensure high resistance of the pipeline against extensive destruction. Numerical simulation of DWT with the steel sample of full thickness was performed; the steel had К65 strength grade. Parallel finite-element computer code DANCO developed in RFNC-VNIIEF was used for simulations. A detailed description of the rupture formation process required a fine-enough mesh and a supercomputer.

This paper presents the results of experimental and numerical tests on angle members connected by one leg with a single row of bolts. This study was designed to determine which failure mode governs the resistance of such joints: net section rupture or block tearing rupture. Experimental tests were insufficient to completely identify the failure modes, and it was necessary to conduct numerical simulations. Finite element analysis of steel element resistance based on rupture required advanced material modelling, taking into account ductile initiation and propagation of fractures. This was realis

Metallic naval structures can undergo progressive damage from external incidents, affecting their ability to withstand subsequent impacts. Ductile damage is known to be sensitive to the stress state according to two scalars, the stress triaxiality ratio n and the Lode parameter L, that determine respectively the loading type applied and the position of the medium principal stress according to maximum and minimum ones. Ductile damage is studied experimentally with specific geometries targeting specific (n; L) values. Bulge Explosion Tests (BETs) are used for naval structures qualification to im

AbstractFor a number of creep resistant steels, the creep ductiliy decreases with increasing temperature and time. As a function of stress, the ductiity is often describe with an S-shaped curve with an upper and a lower shelf level. As a function of time, the S-shape is inverted. If the ductility is high, the rupture is referred to as ductile, and for low ductility levels as brittle. Ductile rupture is believed to be due to a plastic instability such as necking. Brittle rupture on the other hand is controlled by the nucleation, growth and linkage of creep cavities. With the help of the basic m

A methodology is presented for estimating the ultimate structural capability (fragility) of metallic nuclear waste disposal containers (waste packages) subject to impact events. The LS-DYNA finite element analysis (FEA) computer code and massively parallel processing (MPP) is used for nonlinear, dynamic-plastic, large-distortion impact simulations. The fragility estimate for risk assessments uses strain energy concepts, a ductile-rupture damage criterion and tri-linear stress-strain curves adjusted for material cold-forming triaxiality and weldment toughness scatter. FEA examples are provided

Abstract In order to predict the load-bearing capacity of stream generator tubes with defects, this paper proposes a finite element method for analyzing the rupture pressure of SG tube. The simulation is based on the mechanical performance test of 690 alloy, and establishes a plastic constitutive and ductile damage model of 690 alloy. The finite element analysis software ABAQUS is used to establish a finite element model of tubes with defects, and the rupture pressure of tubes with different defect types and crack sizes is analyzed. Comparing the finite element prediction with the model formul

Within the TACIS R2.06/96 project: “Surveillance Program for VVER 1000 Reactors”, sponsored by the European Commission, the local approach of fracture has been applied in the ductile regime. Two different models were applied and compared, namely Tvergaard-Needleman-Gurson versus Prometey model. The main tasks are: • perform special Local Approach experiments on smooth and notched cylindrical specimens; • predict JR-curve on the basis of the ductile fracture models; • compare two models of ductile fracture, namely, the Tvergaard-Needleman-Gurson model and the Prometey model. In this paper, the

The ability to predict the behavior of a crack propagating in a steel natural gas transmission pipeline is of great importance. This is because a long-running fracture is costly, both in terms of the time taken for replacement, and associated lost revenue, and the cost of replacement of the pipe itself. The determination of ductile shear fracture arrest toughness levels requires an accurate knowledge of the gas decompression behavior following the rupture. In particular, there is a need to predict accurately the gas decompression wave velocity within the pipe as a function of initial pressure,

For understanding characteristics of Polymethylmetacrylate (PMMA) under impact, the damage behavior of PMMA plates with various thicknesses (1.5 to 6.0 mm) subjected to ballistic impacts with various velocities (63 to 180 m/s) is experimentally investigated using a specialized testing apparatus. Moreover, numerical simulations using the Finite Element Method (FEM) are conducted for the corresponding experimentally studied cases. Ductile response and brittle tensile failure behavior are considered in the FEM to describe the nonlinear response and the failure mode of the PMMA plates. The numeric
