“…These SMA constitutive models capture part or most of the experimentally observed key points of the phenomenon, including shape memory effect and pseudoelasticity. Studied structures span from SMA pipe connectors Lammering 1993, Nishikawa et al 1991), SMA beams and orthodontic wires Sacco 1999, Gillet et al 1995) to SMA wire reinforced composites (Burton et al 2006, Chen et al 2009, Cho and Rhee 2012, Khalili et al 2012, Wang et al 2011 as well as SMA rotary/torsional actuators and helical springs (Aguiar et al 2010, Chapman et al 2011, Icardi and Ferrero 2009, Prahlad and Chopra 2007, Toi et al 2004.…”

Analytical solutions are derived for the isothermal pseudoelastic response of a shape memory alloy (SMA) thick-walled cylinder subjected to internal pressure. The Tresca transformation criterion and linear hardening are used. Equations are given for the radial and circumferential stresses, transformation strains and radial displacement at various steps of loading and unloading. A structural pressure-temperature phase diagram is provided for the cylinder, analogous to the stress-temperature phase diagram of SMA materials. Pressurization of an initially 100% austenitic cylinder causes the martensite to initially form at the inner radius. For

“…In this paper, taking into account the simplification of both the Tresca yield criterion and the modified Mises yield criterion, ABAQUS finite element simulation software is used to numerically simulate and analyze the body tube model, and analyze the self-tightening pressure required by the body tube in this paper as well as the stresses in the body tube during self-tightening loading and the residual stresses after unloading, with respect to different self-tightening degrees [1][2][3].…”

The self-tightening technology of body tube is to apply a certain pressure in the inner bore of the body tube so that the corresponding residual stress is generated in the body tube, and the self-tightening residual stress can improve the stress situation of the body tube when it is in use and extend its service life. Most of the existing self-tightening body tube research for large-caliber artillery and are simplified to a thick-walled cylinder model, ignoring the internal rifling of the body tube and chrome-plated processing factors, and for the impact load on the body tube and cracks on the self-tightening body tube internal stresses of the impact of the same did not take into account the rifling and chrome layer. In order to address the above problems, this paper takes a small-caliber artillery body tube as the research object, compares the theoretical calculations with the finite element simulation, and carries out the simulation research on the ideal elastic-plastic artillery steel body tube.

User expects his weapon to be light and reliable and to perform multiple times firing per unit time at the same time. In today's technology, the maximum number of firings can be made per unit time with steel barreled weapons, but in composite barrels; many problems occur due to overheating, strength and reliability. Meeting these opposite demands is an engineering problem. In this study, the design of a composite‐steel combination light gun barrel is studied. Firstly, pressure distribution through the barrel has been calculated using Vallier‐Heydenreich method. According to the calculations, analysis has been conducted using both steel barrel and composite barrel. After the analysis, a composite barrel has been manufactured and testing has been conducted on an all‐steel barrel and the manufactured composite barrel. Composite is carbon fiber and resin is epoxy resin. In composite material, carbon fiber is preferred at the rates of 50% and 60%, the material of the steel barrel is AISI 416R stainless steel. The manufactured steel barrels have the same outer diameter but different wall thickness ratios, firing tests were conducted in such a way that the number of shots per unit time was the same.Highlights Stress distribution within a gun barrel was calculated using Vallier‐Heydenreich method. Design and finite element analysis analysis for an all‐steel gun barrel and a composite gun barrel was conducted. A composite gun barrel was manufactured; by using composite materials, the barrel was lightened by 24.8%. The manufactured composite gun barrel and an all‐steel gun barrel were tested by firing over 2500 shots.
