Formability of tailor welded strips and progressive forming test were carried out by Z.Q.Sheng .dome test is the standard test for determining the sheet metal formability.Dome test has been carried out for four material combinations of steels namely DP800 (1 mm thick) CRDQ,DP800 (0.7 mm thick)-CRDQ, results for this questionHow does deformation affect formability?How does deformation affect formability?Therefore,the first major influence on formability is the temperature at which forming is undertaken.Similarly,many materials have good formability when the rate of deformation is low,that is,slow loading.However,these same materials may react in a brittle fashion when undergoing a high rate of deformation,that is,impact or sudden loading.Formability - an overview ScienceDirect Topics
Feb 20,2020 formability of tailor#0183;Abstract Weld zones in tailor welded blanks have different mechanical properties than the base metals and thus have significant effects on formability.In this work,flow stresses of weld zones in laser-welded dissimilar dual-phase steels were measured.
The basic factor influencing the formability of tailor-welded blanks is the hardening of the weld joint and the heat-affected zone during the welding process ,and uneven strain distribution in forming blank.So it is require to pay attention of stress and strain states of TWB during forming for success for Cited by 2Publish Year 2020Author Yong Chan Hur,Daeyong Kim,Byung Min Kim,Chung Yun Kang,Myoung-Gyu Lee,Ji Hoon KimCiteSeerX Formability of steel and aluminium tailor CiteSeerX - Document Details (Isaac Councill,Lee Giles,Pradeep Teregowda) In the industrial production of metallic components by plastic deformation processes,the introduction of the Tailor-Welded Blank (TWB) technological concept enabled,simultaneously,the production of stronger and light panels and the reduction of material waste,which is an important step in nowadays environmental

For each thickness combination,a series of specimens varying in width,height and radii of cut-off were used for formability analysis.Nd:YAG laser was used to butt-weld different tailor-made blank specimens for uniaxial tensile tests and Swift tests.Circular grid analysis wasFormability of tailor-welded strips and progressive Tailor-welded blanks have been widely used in automotive industries.Tailor-welded strips are new type of strip materials for progressive forming.Dome test has been conducted to investigate the
The effects of thickness ratios and seam radius on the formability of tailor-welded blanks with curved seams and straight seams are deduced,separately.In the end,the relationships between the shapes of welding seams and forming heights,and relationships between the thickness ratios and forming heights are given,which are valued to the designers and processers of tailor-welded blanks.People also askWhat are the properties of formability?What are the properties of formability?Formability properties,such as hardness,tensile strength and fatigue strength depend on heterogeneity in the microstructure across the LWBs and is represented by the limited dome height (LDH) obtained in formability tests.In general,formability can be related to the hardness and strength of a weld.Formability - an overview ScienceDirect Topics
