Blog posts

Reliability Block Diagram (RBD), Fault Tree Analysis (FTA), Event Tree Analysis (ETA) and Bayesian Network have been said to be useful tools in the Safety and Reliability class. How reliable is this? Can we discuss if this is true.

Dear Colleague

i cant read the odb file from the abaqus result, please tell how can i fix it or read it. Thanks 

People say that by 2040 the energy landscape
will definitely change. It is also believed that by 2040 the global energy demand
will be increased by 30% while the population is
expected to be increased by 25%.
How will these affect the industries? What are the risks associated? Undoubtedly,
fossil fuels will remain the world's
major sources of energy (at least 50% t of the world's energy supplies). That

Hi,



I got a simple 2D problem (a rectangular shell, static general, CPS4R element), with 557 nodes, each of them have 2 DOFs (U1 and U2), according to the data file. But when I print out the ELEMENT STIFFNESS MATRIX, for each element it is a 12x12 matrix which means the rotational DOF about z axis is also taken into account. How can I omit this 3rd DOF? Can I?



Thank you.
