Experimental investigations on the crush behaviour of AA6061-T6 aluminum square tubes with different types of through-hole discontinuities

Design Optimization of Crashworthiness in Square Tube as Thin Walled Structure With Variations of Crush Initiator: Stripe-Parallelogram-Trigon

“…Eren et al (Eren, et al, 2009) juga sudah melakukan penelitian mengenai crush initiator tipe rib pada front side rail dengan menggunakan metode elemen hingga eksplisit dengan ANSYS/LS-DYNA. Tabung persegi aluminium AA6061-T6 dengan through hole-discontinuitas juga diinvestigasi oleh Cheng et al (Cheng, et al, 2006) dengan mendapatkan kapasitas penyerapan energi saat tabung tersebut diberikan beban aksial secara kuasi statik. Zhang et al (Zhang, et al, 2009) melakukan eksperimen terhadap tabung persegi aluminium yang diberikan buckling initiator dengan menerapkan pulling strip dengan tujuan mendapatkan penyerapan energi.…”

Design of Thin Wall Structures for Energy Absorption Applications: Design for Crash Injuries Mitigation Using Magnesium Alloy

“…A value of unity of the energy absorber member represents an ideal energy absorber which represents a value of the crush force efficiency corresponding to the constant loaddisplacement curve [22], while the low values indicate happening of greater peaks of force during crushing [23]. Low values of crush force efficiency means high peaks force which leads to increasing in acceleration and potential damage to the passengers during frontal impact which must be avoided.…”

Effect of quadrilateral discontinuity size on the energy absorption of structural steel profiles

“…Other studies have focused their efforts in the implementation of geometrical discontinuities to reduce the peak load value. Many shapes of imperfections have been analyze such as circular [2,4,5], slotted [13], elliptical [9] and dimples [8]. In all cases the effectiveness of discontinuities have been corroborated, nevertheless according to Szwedowicz et al [18] the energy abortion capacity also can be modified by location of imperfections along the structure.…”
