K1c for my material is approx 60 MPa.m^0.5 thickness of the fillet including wall is 20mm. I have tried arbitary sucface upto 19 mm deep and got maximum 40 MPa.m^0.5 of K1.&nbsp;&lt;br&gt;* can any one explain this is not reaching over 60?&nbsp;&lt;br&gt;* is there any things specific need to add into material properties for facture analysis?&lt;br&gt;* need to find&nbsp;&lt;span lang=&#8221;EN-GB&#8221;&gt;largest tolerable crack size for brittle failure&lt;\/span&gt;.
