<p>I am performing a piping analysis in ANSYS Workbench using transient thermal<\/strong> and static structural<\/strong> analyses. The setup is as follows:<\/p><\/p>\n

    \n
  1. Pipe Geometry<\/strong>: Length = 2450 mm, Material = SS304L (<span class=”katex”><span class=”katex-mathml”>α=17.5×10−6 K−1<\/span><\/span>).<\/li>\n
  2. Temperature<\/strong>: Reference temperature = 313 K, Cryogenic temperature = 90 K.<\/li>\n<\/ol>\n

    <p>The hand calculation for thermal contraction using <span class=”katex”><span class=”katex-mathml”>ΔL=α⋅ΔT⋅L<\/span><span class=”katex-html” aria-hidden=”true”><span class=”base”><span class=”mbin”>⋅<\/span><\/span><span class=”mord mathnormal”>L<\/span><\/span><\/span> gives <span class=”katex”><span class=”katex-mathml”>−9.56 mm<\/span><\/span>. However, the deformation result in ANSYS differs.<\/p><p>Questions<\/strong>:<\/p><\/p>\n

      \n
    1. Should the deformation in ANSYS match the hand calculation? ansys showing 8.78mm why ?<\/li>\n
    2. How do I ensure the reference temperature is correctly applied in the analysis?<\/li>\n
    3. Are there other factors in ANSYS (e.g., boundary conditions or gradients) that might affect the result?<\/li>\n<\/ol>\n","protected":false},"template":"","class_list":["post-398401","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
