Stress and strain based fracture forming limit curves for advanced high strength steel sheet

In this work, strain based fracture forming limit curve (FFLC) of advanced high strength (AHS) steel grade 980 was determined by means of experimental Nakajima stretch-forming test and tensile tests of samples under shear deformation. During the …

A new approach to evaluate bending forces for deep-drawing operations of a TRIP700 +EBT steel sheet

In this work, a new approach was developed to determine the bending, unbending and friction forces involved in deep-drawing processes of metallic sheets based on a sheet drawing-bending test. The procedure used both the experimental and deduced …

Study on springback from thermal-mechanical boundary condition imposed to V-bending and L-bending processes coupled with infrared rays local heating

This paper shows differences of thermal-mechanical boundary condition and springback between V-bending and L-bending processes. Although a recently conducted study showed that an infrared (IR) local heating method substantially reduces springback …

Numerical investigation of an arc inlet structure extrusion die for large hollow sections

This paper aims to improve the working life of extrusion dies by optimal structure design, which plays an important role in mass production. First, an arc-shaped inlet die structure for an aluminum large-hollow-section profile was developed.

From elastic homogenization to upscaling of non-Newtonian fluid flows in porous media

Upscaling behaviors of heterogeneous microstructures to define macroscopic effective media is of major interest in many areas of computational mechanics, in particular those related to materials and processes engineering. In this paper, we explore …

Über diese Zeitschrift

· The International Journal of Material Forming is the official Journal of the European Scientific Association for material FORMing (ESAFORM) (www.esaform.org).

The Journal publishes and disseminates original research in the field of material forming. The research should constitute major achievements in the understanding, modeling or simulation of material forming processes. In this respect ‘forming’ implies a deliberate deformation of material.

The journal establishes a platform of communication between engineers and scientists, covering all forming processes, including sheet forming, bulk forming, powder forming, forming in near-melt conditions (injection moulding, thixoforming, film blowing etc.), micro-forming, hydro-forming, thermo-forming, incremental forming etc. Other manufacturing technologies like machining and cutting can be included if the focus of the work is on plastic deformations.

All materials (metals, ceramics, polymers, composites, glass, wood, fibre reinforced materials, materials in food processing, biomaterials, nano-materials, shape memory alloys etc.) and approaches (micro-macro modelling, thermo-mechanical modelling, numerical simulation including new and advanced numerical strategies, experimental analysis, inverse analysis, model identification, optimization, design and control of forming tools and machines, wear and friction, mechanical behavior and formability of materials etc.) are concerned.

Papers should describe new forming processes, experiments, models or modelling techniques, related to forming or the relation between process conditions and product properties. In general, simulation results should be validated by experiments unless the focus is purely on novel modelling techniques. New models or modelling techniques should have a broad applicability in forming simulations and should not be restricted to one particular shape.

Results of analytical or numerical models that are not translated into new knowledge or are not supported by experimental validation will not be accepted. Similarly, submissions that describe experimental results without thorough evaluation and conclusion and thus not leading to new knowledge, will be rejected. The relevance for forming technologies and the novelty of the work should be clearly described in the abstract.

Industrie 4.0 und die Möglichkeiten des Digitalen Zwillings

Die Welt der industriellen Automatisierung erlebt gerade einen bedeutenden Umbruch – hin zur Industrie 4.0. Der Ansatz, Dinge zu bauen und danach irgendwie hinzubiegen, hat viel zu lange die Entwicklung neuer Projekte bestimmt. Stattdessen brauchen die Hersteller einen systemorientierten Ansatz, der sich bereits in Entwicklungsprozessen multidisziplinärer Systeme bewährt hat. Jetzt gratis downloaden!
