With the increasing demand for miniaturization of components and parts used in industrial and research applications, the need arose for testing systems capable of handling microscopic and millimeter samples that require accurate measurements of loads and displacements.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 17px;\">\u00a0The main objective of the current study is to design and build a miniature, low-cost, comprehensive testing system that performs tensile, compression, and bending tests to investigate the behavior of miniature samples under different loads. The implemented system involves a mechanical aluminum frame, a stepper motor-based drive system with lead screw for linear motion, a force measurement load cell, and a Linear variable differential transformer (LVDT) displacement sensor mounted in the direction of displacement. Arduino was used as a microcontroller, and the LabVIEW platform was used to control the device, data display, and acquisition in real time during testing. Specialized accessories were designed and applied to perform tensile, compression, and bending tests. A series of tests was conducted on various samples to verify the device&#8217;s reliability and efficiency.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 17px;\">\u00a0The results showed the device&#8217;s ability to measure loads and displacements accurately and to plot stress-strain curves well. The experimental results showed that the tensile test gave an ultimate tensile strength of 258 MPa for the enameled copper wire, this is in agreement with the values \u200b\u200breported in the data sheet for annealed copper wires (216-294 MPa). In addition, the three-point bending test gave a flexural strength of 7151 MPa (7.151 GPa) for the optical fiber (SMF-28), which is consistent with the failure stress range reported in the references for fused silica optical fibers (7.0\u20137.3 \u00b1 0.1 GPa).<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 17px;\">\u00a0The compression test proved the ability of the developed device to perform micro-compression tests and to continuously acquire the related mechanical response.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 17px;\">\u00a0The results obtained show the successful operation of the developed miniature testing system and indicate its potential as a low-cost and versatile platform for the characterization of the mechanical behavior of micro-scale materials.<\/span><\/p>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;6942&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;6943&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;6944&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;6945&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_column_text css=&#8221;&#8221;] On Monday, August, 24 ,2026 Al-Khwarizmi College of engineering held a master thesis defense &#8230; <a class=\"cz_readmore\" href=\"https:\/\/en.kecbu.uobaghdad.edu.iq\/?p=6940\"><i class=\"fa czico-132-arrows-8\" aria-hidden=\"true\"><\/i><span>more<\/span><\/a><\/p>\n","protected":false},"author":27,"featured_media":6946,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_lmt_disableupdate":"","_lmt_disable":"","footnotes":""},"categories":[3,1],"tags":[],"class_list":["post-6940","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-latest-news","category-uncategorized"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.7 -
