Analysis of forming thin titanium panels with stiffeners

Autor: Adamus J., Winowiecka J., Dyner M.

Publikováno v: Archives of Metallurgy and Materials, Vol 62, Iss 1, Pp 173-180 (2017)

The growing demand for light and durable products has caused an increase in interest in products formed of thin sheets. In order to ensure sufficient stiffness of the drawn - parts, stiffening is often performed. Unfortunately, during the forming of

Experimental And Theoretical Determination Of Forming Limit Curve

Autor: Adamus J., Dyja K., Motyka M.

Publikováno v: Archives of Metallurgy and Materials, Vol 60, Iss 3, Pp 1881-1886 (2015)

The paper presents a method for determining forming limit curves based on a combination of experiments with finite element analysis. In the experiment a set of 6 samples with different geometries underwent plastic deformation in stretch forming till

Forming Of Spherical Titanium Cups From Circular Blanks With Cutouts On The Perimeter

Autor: Lacki P., Adamus J., Więckowski W., Winowiecka J.

Publikováno v: Archives of Metallurgy and Materials, Vol 60, Iss 2, Pp 829-834 (2015)

Despite substantial demand for drawn parts made of high-strength sheet metal (including titanium alloys) observed in the modern industry, particularly automotive and aviation, their application remains insignificant. This results from the fact that s

Uniform linear bound in Chevalley's lemma

Autor: Adamus, J., Bierstone, E., Milman, P. D.

We obtain a uniform linear bound for the Chevalley function at a point in the source of an analytic mapping that is regular in the sense of Gabrielov. There is a version of Chevalley's lemma also along a fibre, or at a point of the image of a proper
