As a general thumb rule, if in a cuboid, the ratio of the largest dimension to the smallest dimension is less than 10, then it is
suggestedpreferable to designate the element forasa Solidcandidate.
For example , in asamplethe cuboid, if we takecall the largest dimension "L" , Secondthesecond largest dimensionas"B" and the smallest one as "T" like ( L>B>T) , there may be three conditions :
(1) If L/T <10 (then obviously B/T<10) ,<10), then the element
iseligibleforcanbesettoa solid.
(2) If L/T >10 but B/T <10 , then the element is more like a member than a solid or a plate element.
(3) If L/T >10 and B/T >10 , then the element is more likeaplate(
