vibration test fixture design

Hello all,
I am a fresher; I just started working for a company leading in passenger cars.
I have been given a project in which I have to design a vibration test fixture for passenger car bumper.
Currently, we manufacture fixture in-house. And for every bumper, separate fixture is made.
My task is to design a test fixture (for testing frequency range of 0- 70 Hz) which will be modular.

Microindentation & Fracture of Mineral Rock

The use of Microindentation has proven to be a crucial tool for rock mechanics related studies. For example, Microindentation has been used to advance studies in excavation by allowing further understanding of rock mass properties and its separation. Microindentation has been used to advance drilling studies to improve drill heads and improve drilling procedures. Microindentation has also been used to study chalk and powder formation from minerals.

Paper Roughness Measurement With 3D Profilometry

Paper surface topography is vital to the intended use and quality of the product. To control paper product quality it will heavily rely upon quantifiable, reproducible and reliable surface measurement. Precise surface measurement and evaluation of a paper product can lead to the best selection of processing and control measures. The Nanovea 3D Non-Contact Profilometer utilize chromatic confocal technology with unmatched capability to measure paper surfaces.

Hello everybody,
I am trying to model a plate (shell elements) supported on rubber bearings and columns (beam elements) and I would like to know how to release rotational degrees of freedom at one or both ends of a beam element in Abaqus/Explicit.
Unfortunately, the keyword *RELEASE only works in Abaqus/Standard.
Thanks in advance for your kind help. Regards,

The Understated Contributor to International Economic Recovery

While R&D topics continue
to lead as a beacon for economic recovery, a crucial part of the R&D process
continues to receive little to no attention. And make no mistake, you are about
to learn of the single most important factor in the advancement of new or
improved material technologies around the world.

Literature regarding the appearence of cracks in steel. Thermal, pressure fatigue

Choose a channel featured in the header of iMechanica: 


I am wondering if anyone could recomend som literature for me to get my hands on.
If there is any literature regarding how the appereance of a crack in a piece of thin metal (~0,5mm - 1 mm) could be related to pressure fatigue or thermal fatigue.
Does the crack due to thermal fatigue have a specific appereance and so on. I need get my hands on practical pictures and so on, not equations.
Are there any signs in the vicinity of the crack that is indicating that this could be due to pressure fatigue.

Any help is much appreciated.

Material Testing Machines

Can anyone guide me how to get crosshead speed range equal to or greater than 1:3000 in a motorized electromechanical material testing machine? The load capacity should remain same even at lowest speed.

Soil Pile imteraction in ANSYS ASAS-NL


In order to model a jacket supported by four piles I need to model the interaction between soil and piles in ANSYS ASAS-NL. As I want to make a trasient analysis I use ASAS-NL which unfortunately do not interact with SPLINTER. The jacket structure is modelled by 3D beam elements. Can someone tell me how I model the soil pile interaction? Is it possible to make use of P-Y and T-Z curves in ASAS-NL?


Hi all,

     Currently, I am using ANSYS 12.1 for the fatigue crack propagation simulation for the edge crack & center crack plates. It is a mixed mode crack propagation.


Can anybody please tell me or guide me how to write the code in the ANSYS using APDL for automatic remeshing around the cracktip when crack propagates to the new position?

 Thanks in advance. :) 

Simple Open Source Solver

Choose a channel featured in the header of iMechanica: 

I found the below thread, and thought this would be a good place to ask about open source FEM.


But unlike that thread, I want something that is very simple, that can be run with just a single .exe.  I only need to solve basic structural problems and perhaps eigenvalue problems.  Orthotropic material capability is needed, but input for a composite material via lamina and stacking sequence would be better.

buckling analysis for cylindrical ring

Dear Members Hello


I am conducting buckling analysis for cylindrical ring (Short and thick cylinder) with Lateral Pressure.


I reviewed the basic books ("Buckling of Bars, Plates, and Shells" and "Theory of Elastic Stability" – Timoshenko) and all I could find is buckling of rectangular planes in the axial direction or buckling of cylindrical shells which buckles in the radial direction.

Simulating Hole punching operation using MSC Marc

Does anyone who has previously worked on MSC Marc worked with the concept of element activation and deactivation...?

I need to do a simulation wherein a hole is required to be punched in an alloy steel bar.

The issue is that I am not sure as to how to go about this.

If there is anyone who can guide me through this ..I would appreciate it..!!

Warpage Measurement of PCB With 3D Profilometry

Flatness measurement of electronic parts and assemblies, or PCB’s, has become increasingly critical as geometries become smaller: finer pitches, smaller solder ball volumes, thinner substrates, etc. Additionally, processing temperatures vary and can play a major role in PCB warpage and or planarity defects.

The use of IOSO Optimization and ABAQUS at Civil Structures of NPP (from ABAQUS Users' Conference)

At the stage of NPP civil structure design for determination of stress-strain state (SSS) at static and dynamic loading ABAQUS is widely used. Hereto the floor response spectra are determined for calculation of loadings on the equipment at special dynamic impacts (seismic, air shock wave, aircraft crash). In case if the obtained characteristics of SSS or spectral accelerations exceed maximum permissible values, designers take actions on strengthening the corresponding structural components.

question on double cantilever beam test

I have a beginner's question on DCB testing of polymers. The fracture strength during Mode 1 loading increases with crack length due to the compliance of the test specimen. In other words it becomes harder to induce fracture as the crack length increases.Is my understanding correct?




Acurate Size Measurements of Nano Particles and Nano Pores Make Mechanical Understanding Easy

Encouraged by its current and prospective customers, Ebatco’s Nano Analysis and Testing Laboratory (NAT Lab) has expanded its nano/micro scale analytical and measurement capabilities significantly.

IOSO application for casting processes

Dear Colleagues,

New practical case studies made with the aides of IOSO in new engineering fields prove universal capabilities of IOSO Optimization Technology applicable to wide variety of real-life problems. Let us provide you the brief description of the problem that was solved by Italian engineering consultancy company XC Engineering for the well-known Swiss production firm Buhler. The problem was to search for the optimal velocity of the piston in an HPDC process.

Micro Scratch Testing CrN Coating on Titanium Alloy

Specific Coatings are used to further increase performance of titanium alloy parts at elevated temperatures. More specifically, Chromium Nitride (CrN) Coatings are designed to perform under conditions of high load and temperature. By using scratch testing it is possible to detect premature adhesive failure of the CrN coating in real-life applications.
