alkej-79	Mohammed, Adnan D.; Ibraham, Hawraa S.	تقدير طاقة الاهتزاز لصفيحتين متصلتين (ملحومة) باستعمال طريقة تحليل الطاقة الإحصائي	2011	14	.pdf	application/pdf	5647	248	67	The equation for the net power transmitted from sub-systems i to j is׃­ jjiiijijtrans EEP ωηωη −=, … (4) Where, ijη , jiη is the coupling loss factor from sub-systems i to j and from sub-systems j to i respectively and it depends on the type of connection between sub-systems, the material properties, the dimensions of the system and the center frequency of the band, ω (rad/sec) Ref. The aim of this work is to find the energy stored in the sub-systems for two coupled (welded) plates in rectangular angle systems and study the effect of changing sub-systems dimensions, the results shows that as surface area of directly driven plates A1 increases energy level of plate 1 increases while a reduction in the energy level of indirectly driven plate (plate 2) is noticed.	cache/alkej-79.pdf	txt/alkej-79.txt
