Dynamic extended SIFs under P- and S-waves
Dynamic extended stress intensity factors near-fields radiation distribution for P- and S-waves at the 3D crack surface
related to thermal analysis
hello friend
my self raj .
in the beam and shell element " thermal OR temparature vs time" transient analysis possible ?
i have four story building model , if apply a temprature vs time history at second floor then can i find out the each floor tempreture at each time steps ? due to thats also find out the strees and moment or force at each node due to elongation of beam sheel element due to temparature incraese.
EM388F Term Paper: Finite Element MEthod in Fracture Mechanics
Early applications of the finite element method to crack problem was
developed by Swedlow and et al. Even though they could get reasonable
accuracy about 5 to 10%, later study showed that solutions in the
vicinity of the crack tip cannot be guranteed to be accurate regardless
of the mesh density around tip. In order to overcome this problem,
people developed special crack tip elements.
In this term paper, I'm going to present 1) Finite Element Method in
Fracture Mechanics and 2) NewFinite Element technique so called Extended Element Method.
EM 388F Term Paper: Application of Fracture Mechanics on Cortical Bone Studies
One of the most common problems in older people is the fragility of the bones. Human bones are prone to fracture, and fracture of certain bones in the body such as the cortical bone may be fatal. Understanding of the fracture mechanism of bones is essential for the medical profession, and plays a major role in the study of osteoporosis as well.
EM 388F Term Paper: Subcritical Cracking of Low-k Dielectrics
Abstract
With the scaling of VLSI, ultra low-k dielectrics with porosity are being introduced to reduce the capacitance coupling. But due to the weak bonding strengths, low-k dielectrics may fail by environmental-assisted subcritical cracking, fracture at stresses far below the loads required for catastrophic failure, causing reliability issues. In this term paper, several references are reviewed to investigate the mechanism of subcritical cracking at multiscale levels.
