I&rsquo;ve attached a picture to help address your question. I&rsquo;m already familiar with how the Mohr-Coulomb safety tool calculates the safety factor. In geomechanics, it&rsquo;s a well-known fact that shear failure typically occurs around the hole in the direction of the minimum horizontal stress, where the hoop stress is highest. In my case, minimum horizontal stress is 3.23 MPa, acting in the X-direction. Therefore, the factor of safety in these areas should be less than 1. However, the Mohr-Coulomb safety tool is showing a safety factor greater than 1 in these regions. Could you help clarify why this safety tool contradicts a geomechanical fact?&lt;\/p&gt;&lt;p&gt;Regards,&lt;\/p&gt;&lt;p&gt;Faysal&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/05-11-2024-1730785136-hoop.jpg\" alt=\"\" \/>&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-392698","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hello Pedram,Thank you for your response.
