In this Paper, the nonlinear free and force vibration of a single-walled carbon nanotube (SWCNT) with simply supported ends is
investigated based on von Karman’s geometric nonlinearity. The SWCNT described as an individual shell and the Donnell’s
equations of cylindrical shells are used to obtain the governing equations. The Galerkin's procedure is used to discretized partial

Special Saint-Venant's Principe of the “ Hole in Plate” Problem

Submitted by Jian-zhong Zhao on
research

The problem of the
infinite plate with a central hole loaded by an equilibrium system of forces is
generalized and its formulation of Special Saint-Venant's Principle is
established. It is essential to develop mathematical theories of Special
Saint-Venant's Principle one by one if Elasticity has to be constructed to be
rational, logical, rigorous and secure mechanics.

Saint-Venant's Principe of the Problem of the Cylinder

Submitted by Jian-zhong Zhao on
research

The problem of the
infinite axisymmetrical circular cylinder loaded by an equilibrium system of
forces on its near end is discussed and its formulation of Special
Saint-Venant's Principle is established. It is essential to develop
mathematical theories of Special Saint-Venant's Principle one by one if
Elasticity has to be constructed to be rational, logical，rigorous and secure mechanics.

Modified Saint-Venant's Principe of the Problem of Curved Bars

Submitted by Jian-zhong Zhao on
research

The proof of
Saint-Venant's Principle for curved bars is discussed and the formulation of
Modified Saint-Venant's Principle of the problem is established. The study
shows that Saint-Venant's decay of stresses is valid only for the curved bars
which are “effectively infinite”. It is essential and significant to develop

quenching

 hello everyone.

 

iam devarajan.k currently pursuring M.Tech in Engineering Design in Amrita University and doing projects on hot rolling of thick plates.For FEm simulation iam using ABAQUS software. After material rolled, i want to quench that material into water or some other material. i dont know how to do this in abaqus. please guide me if any one know this. please

 

With Regards

Applying load on a Compact Tension specimen in Abaqus

Submitted by Chizyuka on
education

Hi there,

I have been trying to model fracture toughness test in abaqus but unfortunately I am faced with difficulties of how to apply the tensile loading on the compact tension model's pin holes. Most papers I have come across show only pressure being applied on the flat upper most edge of the test specimen instead of the pin holes. Please could there be someone out there who could show me how to apply this tensile loading right on the holes?

Thanks in advance.
