draw the mass gain curve over time
Hello
I want to draw the mass gain curve over time, it follows the Fick law but the results I obtained are either instantaneous or ramp.
how to draw?
thank you

Square to parallelogram
I am trying to model a rigid box which deforms into a parallelogram on application of
displacement/velocity. I have made a box using 4 rigid plates ,but when I apply
the shear force the plates lose contact. I have used no seperation technique
it didn't help .kindly give a solution asap.
Fillet Weld in ABAQUS
Forums
Choose a channel featured in the header of iMechanica
Hello everyone,
I want to model a connection between two steel plates which form a T-section. The welds are fillet weld. Do you have any recommendation how to model the weld? One way I think of is to connect the two plates with two solid elements weld through tie constraint. You think that's a right way of doing that?
Excessive rotation of Nodes/ ABAQUS explicit
Choose a channel featured in the header of iMechanica
I am simulating dynamic impact using B31 element type and general contact in ABAQUS Explicit and the job is aborted showing the error of "Excessive rotation of nodes". I, also, used mass scaling to control the run time.
Does anyone know how to control this problem?
I really appreciate your replies.

A short note on equal peak design for the pendulum tuned mass dampers
By: A. Deraemaeker and Payam Soltani
Abstract:
Pendulum tuned mass dampers (PTMDs) are used to passively mitigate the vibrations of tall structures and buildings. The main objective of this short note is to introduce analytical formulae for the optimum design of the linear PTMD coupled to an undamped primary system. Den Hartog's equal peak method is applied to derive the optimum design. With the mass ratio between the primary system and the PTMD, the optimum length and optimum damping of the pendulum are calculated. The formulae are presented in both dimensional and non-dimensional forms and are simple to apply in real applications. It is also shown that the vibration mitigation performance of the proposed optimum design precisely matches the results obtained by numerical optimisation techniques.

Journal Club Theme of June 2016: 2D Materials: Current and Future Directions
Two-Dimensional (2D) materials have been widely studied since the discovery of graphene in 2004. Many of the initial works on the various 2D materials (graphene, MoS2 and other transition metal dichalcogenides, black phosphorus, and others like the monochalcogenides) by mechanicians focused on issues like ideal strength, and appropriate methods to calculate the bending modulus. Some of these, and other issues, were reviewed by Sulin Zhang in a J-Club from March 2015 (http://imechanica.org/node/17999). That was a nic
