Research of stress distribution in the cross-section of a bimetallic perforated plate perpendicularly loaded with concentrated force

Abstract

The paper presents the stress distribution along the plate thickness in a bimetallic steel – titanium circular, axially symmetrical perforated plate produced in the technological process of explosion welding. The steel layer is the layer that transfers the load in the plate, while the titanium layer is used to improve the properties of the plate, e.g. corrosion resistance, thermal transmittance, etc. in the plate. Two cases of fastening were considered, i.e. a freely supported and fixed plate. Such plates are used in various engineering structures, e.g. simply supported plates can be used in loose material screens, while plates are fixed in heat exchangers. The load was assumed as a concentrated force applied perpendicularly to the plate surface. The results obtained numerically using the finite element method were compared with the results calculated according to the analytical equations. It has been shown that the difference in the results of equivalent von Mises stress calculations does not exceed 13%. The research results presented in the paper can be used by engineers to design bimetallic perforated plates perpendicularly loaded to their surface.

Modeling of the Temperature Regimes in a Layered Bimetallic Plate under Short-Term Induction Heating

“…Such elements are affected by various physical factors, such as power, thermal, and electromagnetic ones, while technological functioning and operation. There are certain studies of the power and thermal factors that influence the temperature distribution in bimetallic plate elements [17][18][19][20][21]. In [17], the joining of layers of the Al-Cu bimetallic composite and the diffusion process on edge between the layers using hot rolling are analyzed.…”

“…Dong et al in [20] proposed three-dimensional models of finite elements to study the pre-bending process and a bimetallic pipe formation. Konieczny et al in [21] presented a numerical and analytical study of the stress distribution along the plate thickness in circular axisymmetric perforated steel-titanium bimetallic plate. The results were obtained numerically using the finite element method.…”
