| סיכום: | Nowadays, there are many applications in which need the combination or different
materials. The development of this is caused by the mechanical wear problem, a
high temperature situation or other conditions in which different properties are
required from different parts of the same applications. This problem brings about the
need for joining dissimilar materials. However the combination process between two
dissimilar materials can caused mechanical mismatch and may lead to catastrophic
failure or crack. Hence, this study will focused on the stress intensity factor on edge
crack between dissimilar joint plates. The study focused on the investigation of
edge crack behavior of dissimilar joint plates and to find out stress intensity
factor (SIF) of dissimilar joint plates under different conditions by using finite
element software. In this research, the investigation simulation are conducted by
using finite element analysis software, ANSYS. A program that consist a coding of
joining dissimilar material with centre and offset edge crack have been developed
using ANSYS software. Data of stress intensity factor, K produced by ANSYS
software then transform to dimensionless stress intensity factor, F. Relationship
between mechanical mismatch, α, ratio of stress, β, relative crack depth, a/w and
relative offset distance, b/h to the dimensionless SIF, F are analyze and discussed. |
