In this paper, we will focus on the types of roof’s brick used
in construction and theoretically compare thermally between
different kinds in the local market, and finally we will propose a
new form of roof’s brick give the optimal insulation without
increasing the weight.
This study aims to investigate the effect of the alveolar ridge shape in
the distribution of stress at the lower removable partial dentures
supported by implants using a finite element method, with four models
for a half mandible are designed with
a free end saddle using an
ANSYS program and Canine was abutment, where the remaining ridge
is representing the four alveolar ridge shapes (horizontal and distal
descending and concave and distal ascending), two removable partial
dentures were designed for each model one supported by tooth and
fibromucosa and another one supported by tooth and implant, it has been
applied a load of 50 Newton on all models and has been studied stress
equivalent for each model.
The telescopic cantilever beam is widely used in different types of cranes. These
structures are flexible; it can expand or shrink according to the operating conditions. The
dynamic changes of the total length of the structure lead to time-dependen
t vibrational
characteristics. In practice, CAD modeling for this case is a challenging matter due to the
nature of the problem of analyzing stress and deformation occurring during the operation
of the crane. This research discusses the feasibility of finding a solution for the design
problems initialized during the failure of the telescopic cantilever beam through the
application of Finite Element Analyses (FEA) in order to find the ideal dimension of the
structure which represents the best design for the telescopic cantilever beam.
