Plane Strain Deformations of Locking Materials near a Crack Tip
Plane-strain deformations of an isotropic and homogeneous Hookean body containing a crack are studied and it is required that the dilatation everywhere in the body be. greater than or equal to a constant. Following Prager, the region where the dilatation always equals the constant is identified as the locking region. For the case when the deformations of the body are symmetrical about the plane...
متن کاملPre-Analysis Locking: A Safe and Deadlock Free Locking Policy
A safe and deadlock free lock policy is introduced, called pre-analysis locking. Pre-analysis locking is based on an efficient geometric algorithm which inserts lock and unlock operations into the transactions. Pre-analysis locking is the first safe and deadlock free general locking policy which is not a variant of two-phase locking. It is an approach conceptually different from policies follow...
متن کاملBending-Unbending Analysis of Anisotropic Sheet under Plane Strain Condition
The mechanical behavior of cold rolled sheets is significantly related to residual stresses that arise from bending and unbending processes. Measurement of residual stresses is mostly limited to surface measurement techniques. Experimental determination of stress variation through thickness is difficult and time-consuming. This paper presents a closed form solution for residual stresses, in whi...

متن کاملKinematic analysis of a posterior-stabilized knee prosthesis.
BACKGROUND The goal of total knee arthroplasty (TKA) is to restore knee kinematics. Knee prosthesis design plays a very important role in successful restoration. Here, kinematics models of normal and prosthetic knees were created and validated using previously published data. METHODS Computed tomography and magnetic resonance imaging scans of a healthy, anticorrosive female cadaver were used ...
