Tensile stress of the concrete
Dear friends
The obtained results from my model show that the ultimate load is higher
than the expected one. after checking the results, I found out that the
tensile stress of concrete is much higher than input value for the
tensile yield stress. "concrete damaged plasticity model" is applied.
your help is highly appreciated.

Empirical observations of temperature
I have divided the old notes on temperature into three parts:
- Principle of the conservation of energy
- Empirical observations of temperature (this part)
- Energy and fundamental postulate
Our feeling of hotness comes from everyday experiences. These experiences indicate that many levels of hotness exist, and that all levels of hotness can be mapped to a real variable.
Two Postdoctoral Positions at School of Mechanical & Aerospace Engineering, Nanyang Technological University, Singapore
Enthusiastic and highly motivated postdoctoral scientists are sought to work with Dr. Kun Zhou at the School of Mechanical and Aerospace Engineering, Nanyang Technological University, Singapore on the following areas:
Post Doc Fellow Position at The Rehabilitation Institute of Chicago
A full time Postdoctoral position is available immediately in the Sensory Motor Performance Program at The Rehabilitation Institute of Chicago.
Under the general supervision of the assigned Senior Research Scientist, the Post Doc Fellow will be responsible for the development of a three-dimensional multi-scale finite element model of the human knee, and will compute the stress/strain fields in the joint soft tissues before and after common orthopaedic surgeries using three-dimensional hyper-elastic formulation.
Ph.D. Studentships in Composite Materials-Chonbuk National University, Republic of Korea
We welcome applications for a fully funded PhD position in the field of experimental mechanics and materials science. Further details in the attachment.
A computational model of hydrostatically coupled dielectric elastomer (HCDE) actuators
Abstract:A hydrostatically coupled dielectric elastomer (HCDE) actuator consists of two membranes of a dielectric elastomer, clamped with rigid circular rings. Confined between the membranes is a fixed volume of a fluid, which couples the movements of the two membranes when a voltage or a force is applied. This paper presents a computational model of the actuator, assuming that the membranes are neo-Hookean, capable of large and axisymmetric deformation. The voltage-induced deformation is described by the model of ideal dielectric elastomer. The forc
