Fine Element Analysis (FEA)
Design Validation Solutions
Designers are constantly under pressure from both their clients and management to increase reliability and longevity, be quicker to market with new, improved products, reduce product weight and cost, and increase productivity. This demanding environment prohibits engineers from testing multiple prototypes and design alterations to gain a better understanding of their designs. Yet, that information is vital for producing innovative, high-quality products.
Fine element analysis allows designers to conduct hypothetical studies in a timely manner to identify the best material and mechanical design for a particular function. Using computational model and analysis software to perform evaluations saves time and money and can help improve overall design performance.
Utilizing analysis up-front in the design cycle allows designers to test multiple design options while still in the initial concept phase. This allows designers to accurately and unambiguously make the best decisions in terms of safety, functionality and cost. Additionally, FEA studies reduce the possibility of investing time and money towards a faulty product. By anticipating design faults before production, designers avoid wasting resources on a defective product.
Our Finite Element Analysis services are to help Product Designers to determine:
• Explore Multiple Design Options
• Reduce Physical Prototypes
• Optimize Design Performance FEA
Using FEA software, SolidMasters can perform virtual testing and analysis of parts and assemblies, predicting the physical behavior of practically any part or assembly under any loading condition.
Drop test, optimization, thermal heat transfer, thermal stress, vibration, fatigue, and buckling analysis services, enabling our engineers to detect design problems in less time than a prototype could be built.
The use of FEA analysis services have a particular value to designers due to the size and complexity of the systems they are developing, FEA analysis services can identify design issues that may elude a designer's review simply because of the dynamic nature of machinery's many moving parts.
The finite element analysis is used to replicate the real world materials in a virtual world. Implementing this into a real time renderer is therefore a great achievement.
Finite element analysis(FEA) entails breaking down of a surface or volume into smaller portion and upon subjecting them to a load or constraint their displacement is calculated giving a result depending on the material the object was defined as being made of and the property it has(plate tube bar etc).
In order to optimize manufacturing factors like cost material weight etc... or to ensure safety structural analysis an efficient process in this regard. This can also be used to scrutinize the varied designs which influence the life and performance of the product.
A Video On The Finite Element Method.
The finite element method is one of the most powerful numerical methods available for solving partial differential equations; which apply over complex shapes. Very often in engineering science it is difficult to solve a partial differential equation which applies over a complicated shape. The process therefore is to sub-divide the complex shape into lots of simpler shapes on which the complex differential equation can be solved. The process then is to solve the complex differential over each simpler shape and 'join' all the simpler shapes together ensuring compatibility and equilibrium at the inter-element boundaries. This often results in thousands of simultaneous equations which can be solved on a digital computer. Writing of the computer program is 'relatively simple' compared with solving such a difficult mathematical problem by traditional methods. The method can be used for structural analysis dynamics vibrations fluid flow thermodynamics acoustics electrostatics magneto statics seepage through porous media electrical and fluid networks electronics etc. etc. Large commercial computer packages are available such as PAFEC ANSYS NASTRAN ABACUS LUSAS etc. etc; which make solution relatively simple for most problems in engineering.

Bridges aircraft wings machine tools and all other physical structures have natural frequencies. A natural frequency is the frequency at which the structure would oscillate if it were disturbed from its rest position and then allowed to vibrate freely. All structures have at least one natural frequency. Nearly every structure has multiple natural frequencies.
Resonance occurs when the applied force or base excitation frequency coincides with a structural natural frequency. During resonant vibration the response displacement may increase until the structure experiences buckling yielding fatigue or some other failure mechanism.
There are many tools available for performing vibration analysis and testing. The frequency response function is a particular tool.
A frequency response function (FRF) is a transfer function expressed in the frequency domain.Frequency response functions are complex functions with real and imaginary components. They may also be represented in terms of magnitude and phase.
The frequency response technique can also be valuable to mechanical engineersstudying things like airplane wing dynamics or chemical engineers studyingdiffusion or process dynamics.
A frequency response function can be formed from either measured data or analytical functions.
A frequency response function expresses the structural response to an applied force as a function of frequency. The response may be given in terms of displacement velocity or acceleration. Furthermore the response parameter may appear in the numerator or denominator of the transfer function.

For just HKD999 each hour of studio time or HKD999 for a fully produced video Video Cha Cha offers truly affordable website video content to start ups entrepreneurs and SMEs in Hong Kong.
(A community service of the Hong Kong Visa Centre -http://www.hongkongvisageeza.com)
Since 2011 at the Hong Kong Visa Centre we have produced hundreds of high quality useful videos and learned the art of making them to a very cost effective formula.
Indeed my co-founder and I have been able to build an entire business around a consistent video content development process.
And so can you.
The Video Cha Cha studio here in Wanchai is where we produce all our Visa Centre videos -- and fellow entrepreneurs are now welcome to use it to record and make your own.
For the novice video entrepreneur we have reduced the art of video production down to writing a script speaking to camera and choosing a template for your final produced video.
All for a cheap as chips price too.
For the more adventurous we have the resources to accommodate documentary training and round table or interview and group discussion productions (including live streaming to the web).
Our philosophy is to bring a truly affordable video service to Hong Kong's entrepreneurs and help you bring your propositions and your websites alive and assist in helping you thrive.
