APLIKASI TEGANGAN-REGANGAN EKIVALEN PADA PERHITUNGAN UMUR FATIK PADUAN AL 6063 UNTUK BEBAN AKSIAL DAN TORSI

H. Agus Suhartono

Abstract


Tension-compression and torsion low cycle fatigue testing were conducted by strain
control on Aluminum alloy 6063 thin wall tube specimens. The relation between type of loading and
deformation characteristics were recordedand analyzedfor calculating equivalent stress and strain.
The Von Misses and Hencky's equation can transform the shear stress-strain into equivalent stressstrain
very good which is proved by experimental result. The life prediction based on the calculated
equivalent straingive a satisfactory resultfor both type of loading.
