रिव्हेटेड जोडची कार्यक्षमता अनपंच केलेल्या स्थितीत प्लेटच्या ताकदीचे गुणोत्तर म्हणून परिभाषित केली जाते.
\(\eta = \frac{{Strength\;of\;riveted\;joint}}{{Strength\;of\;unriveted\;solid\;plate}}\)
रिव्हेटेड जोडची ताकद ही फाटण्याच्या ताकदीवर, कातरण्याची ताकद किंवा जोडाच्या क्रशिंग सामर्थ्यवर अवलंबून असते, कार्यक्षमता फाडण्याची कार्यक्षमता, कातरण्याची कार्यक्षमता आणि क्रशिंग कार्यक्षमता असू शकते.
- फाडण्याची कार्यक्षमता: रिव्हेटेड जोडची फाडण्याची ताकद/अनरिव्हेटेड सॉलिड प्लेटची ताकद
\(\begin{array}{l} {\eta _t} = \frac{{Tearing\;strength}}{{Strength\;of\;solid\;plate}}\\ {\eta _t} = \frac{{\left( {p - d} \right)t\;{\sigma _t}}}{{{p_t}\;{\sigma _t}}} = \frac{{p - d}}{p} \end{array}\)
- कातरण्याची कार्यक्षमता: रिव्हेटेड जोडची कातरण्याची ताकद/अनरिव्हेटेड सॉलिड प्लेटची ताकद
\({\eta _s} = \frac{\pi }{4}\left( {\frac{{{\sigma _s}}}{{{\sigma _t}}}} \right)\left( {\frac{{{d^2}}}{{pt}}} \right)kn\)
k हे प्रभावी पृष्ठभागाचे क्षेत्रफळ आहे (दुहेरी कातरणासाठी, k = 2), n म्हणजे खेळपट्टीच्या लांबीमधील रिव्हट्सची संख्या
- क्रशिंग कार्यक्षमता: रिव्हेटेड जोडची क्रशिंग सामर्थ्य /अनरिव्हेटेड सॉलिड प्लेटची ताकद
\(\begin{array}{l} {\eta _c} = \frac{{Crushing\;strength}}{{Strength\;of\;solid\;plate}} = \frac{{ndt\;{\sigma _c}}}{{pt\;{\sigma _t}}} = n\left( {\frac{d}{p}} \right)\left( {\frac{{{\sigma _c}}}{{{\sigma _t}}}} \right)\\ \end{array}\)
