  <dc:description>&lt;div class="hlFld-Abstract"&gt;&lt;div class="NLM_paragraph"&gt;The recent measurements of the&lt;span&gt;&amp;nbsp;&lt;/span&gt;elastic&lt;span&gt;&amp;nbsp;&lt;/span&gt;constants of calcite by Reddy and Subrahmanyam (1960) disagree with the values obtained independently by Voigt (1910) and Bhimasenachar (1945). The present authors, using an&lt;span&gt;&amp;nbsp;&lt;/span&gt;ultrasonic&lt;span&gt;&amp;nbsp;&lt;/span&gt;pulse technique at 3 Mc and 25°C, determined the&lt;span&gt;&amp;nbsp;&lt;/span&gt;elastic&lt;span&gt;&amp;nbsp;&lt;/span&gt;constants of calcite using the exact&lt;span&gt;&amp;nbsp;&lt;/span&gt;equations&lt;span&gt;&amp;nbsp;&lt;/span&gt;governing the&lt;span&gt;&amp;nbsp;&lt;/span&gt;wave&lt;span&gt;&amp;nbsp;&lt;/span&gt;velocities&lt;span&gt;&amp;nbsp;&lt;/span&gt;in the&lt;span&gt;&amp;nbsp;&lt;/span&gt;single crystal.&lt;span&gt;&amp;nbsp;&lt;/span&gt;The results are&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;C&lt;/i&gt;&lt;sub&gt;11&lt;/sub&gt;=13.7,&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;C&lt;/i&gt;&lt;sub&gt;33&lt;/sub&gt;=8.11,&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;C&lt;/i&gt;&lt;sub&gt;44&lt;/sub&gt;=3.50,&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;C&lt;/i&gt;&lt;sub&gt;12&lt;/sub&gt;=4.82,&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;C&lt;/i&gt;&lt;sub&gt;13&lt;/sub&gt;=5.68, and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;C&lt;/i&gt;&lt;sub&gt;14&lt;/sub&gt;=−2.00, in units of 10&lt;sup&gt;11&lt;/sup&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;dyn/cm&lt;sup&gt;2&lt;/sup&gt;. Independent checks of several of the&lt;span&gt;&amp;nbsp;&lt;/span&gt;elastic&lt;span&gt;&amp;nbsp;&lt;/span&gt;constants were made employing other directions and&lt;span&gt;&amp;nbsp;&lt;/span&gt;polarizations&lt;span&gt;&amp;nbsp;&lt;/span&gt;of the&lt;span&gt;&amp;nbsp;&lt;/span&gt;wave&lt;span&gt;&amp;nbsp;&lt;/span&gt;velocities.&lt;span&gt;&amp;nbsp;&lt;/span&gt;With the exception of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;C&lt;/i&gt;&lt;sub&gt;13&lt;/sub&gt;, these values substantially agree with the data of Voigt and Bhimasenachar.&lt;/div&gt;&lt;/div&gt;&lt;div class="article-paragraphs"&gt;&lt;div class="sectionInfo"&gt;&lt;div class="sectionInfo"&gt;&lt;div id="_i1" class="sectionHeading"&gt;&lt;br data-mce-bogus="1"&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</dc:description>
