ÔÚһƪӢÎÄÎÄÏ×Àï¿´µ½ÕâÑùÒ»¾ä»°£º for both element types, integration in closed form is used to evaluate the contribution of normal and shear strains over the cross section of the element. A numerical integration method with one Gauss point is used for the proposed element to evaluate the contribution of strains in the axial direction.

In mathematics, a closed-form expression is a mathematical expression that can be evaluated in a finite number of operations. It may contain constants, variables, certain "well-known" operations (e.g., + − ¡Á ¡Â), and functions (e.g., nth root, exponent, logarithm, trigonometric functions, and inverse hyperbolic functions), but usually no limit. The set of operations and functions admitted in a closed-form expression may vary with author and context. ½âÎö½â£¬ÓÖ³ÆÎª±Õʽ½â£¬ÊÇ¿ÉÒÔÓýâÎö±í´ïʽÀ´±í´ïµÄ½â¡£ ÔÚÊýѧÉÏ£¬Èç¹ûÒ»¸ö·½³Ì»òÕß·½³Ì×é´æÔÚµÄijЩ½â£¬ÊÇÓÉÓÐÏ޴γ£¼ûÔËËãµÄ×éºÏ¸ø³öµÄÐÎʽ£¬Ôò³Æ¸Ã·½³Ì´æÔÚ½âÎö½â¡£¶þ´Î·½³ÌµÄ¸ù¾ÍÊÇÒ»¸ö½âÎö½âµÄµäÐÍÀý×Ó¡£ÔÚµÍÄê¼¶ÊýѧµÄ½Ìѧµ±ÖУ¬½âÎö½âÒ²±»³ÆÎª¹«Ê½½â¡£ µ±½âÎö½â²»´æÔÚʱ£¬±ÈÈçÎå´ÎÒÔ¼°¸ü¸ß´ÎµÄ´úÊý·½³Ì£¬Ôò¸Ã·½³ÌÖ»ÄÜÓÃÊýÖµ·ÖÎöµÄ·½·¨Çó½â½üËÆÖµ¡£´ó¶àÊýƫ΢·Ö·½³Ì£¬ÓÈÆäÊÇ·ÇÏßÐÔÆ«Î¢·Ö·½³Ì£¬¶¼Ö»ÓÐÊýÖµ½â¡£ |
