Fundamentals of Mechanical Behavior of Metals – Important Tips to Remember

Fundamentals of Mechanical Behavior of Metals

Following are some important tips that you should consider while understanding the fundamentals of Mechanical behavior of Metals:

1. Mechanical Properties measured with the help of Tension tests include modulus of elasticity (E), yield stress (Y), ultimate tensile strength (UTS) and Poisson’s ratio (v). True stress-strain curves are important in determining properties such as strength coefficient (K), strain hardening coefficient (n), strain rate sensitivity exponent (m) and toughness.

2. Compression tests simulate processes like forging, rolling and extrusion. Properties measured by compression test are subject to inaccuracies due to presence of friction and barreling.

3. Bend or flexure tests are performed on brittle materials; the outer fiber stress at fracture in bending is called Modulus of Rupture or transverse rupture strength. The forces applied in bend tests are simulated for processes like, forming of sheet and plate, as well as testing of materials for tool and die.

4. Hardness is related to strength and wears resistance, but it is not a fundamental property of the material.

5. Creep refers to the permanent elongation of a component under a static load maintained for a given period of time. In this a constant tensile load at a given temperature is applied for a certain time, till the material fails by necking and rupture.

6. Residual stresses are those which remain in a part after it has been deformed and all external forces have been removed. The nature and level of these stresses depend upon the way in which the material is plastically deformed. These are removed by heat treatment processes like, annealing.

7. In metal working operations, the job piece material is subject to tri-axial stress, via different tools and dies. Yield criteria provide relationship between uniaxial yield stress for material and stress applied. The two most commonly criterion are; Tresca’s and Von Mises’.

More such tips and tricks can be found at IES Academy blog from where you can get Gate Coaching in Delhi.  IES Academy is one of the famous institutes in Delhi offering coaching for IES, GATE, PSU and other such engineering exams.

IES Academy will provide you the platform whereby you can build up your career successfully in the engineering sector of India. From the institute campus itself, you will be start getting the job opportunities and thus can find a great start ahead in the engineering sector.

How Work Experience Helps You?

A college degree earns you the access to apply for first job interviews. You showcase the knowledge earned during your college days efficiently and that lands you your first job. However, thereafter this does not remain the ultimate tool to accelerate your career growth. Utilizing the first job experiences aptly to make your self more productive and suitable for future career options is what takes you higher on the career graph.

You have an upper hand

The more relevant work experiences you can cite, the greater work opportunities you receive. It is a known fact that employers do look for professionals who have some kind of work experiences related to their business. And sometimes it may weigh more than your theoretical knowledge.

You are more employable

Well, right from your initial days of job search, you will be told by many that it is important to present yourself as a unique and desirable candidate. However, unfortunately, you remain clueless about how to go about it unless you really are in the industry.

Yes presenting yourself as a no match in a crowd of competitive professionals is vital and equally difficult. However, work experiences will slowly bring in those ideas about how you can truly market your unique skills in future job prospects.

You are equipped with enhanced skills:

Any job experience – part time, full time or internships; has loads to offer you. Spending a considerable period in a permanent job will teach you many things listed here, that no other graduating programs or college degrees may offer you.

And when it comes at part time job experiences or internships, you get a brief idea about the real professional world, opportunities to acquire and enhance skills. In addition you also learn if your chosen field or industry suits you. There are many professionals who land themselves in wrong jobs. So, when you engage yourself in part time experiences, you do not remain prone to taking wrong career decisions.

You learn time management:

People who have tasted success say that only because they were capable of managing their time efficiently, they have marched ahead of many.

Now, there are many who either acquire, or are born with this skill. However, there are numerous others who have work experiences teaching them this art every working day. Work experience is something that necessitates time management as a job survival tool. Therefore, people somehow learn this art if they are not blessed to be born with it or did not acquire this during early college days.

You become a team player:

Every organization big or small requires a group of people working towards common targets. Work experiences offer professionals with rewards as well as challenges of working in a team. And in the process, we have exposure to meet number of people belonging to different backgrounds;thus we become good listeners, we learn the act of seeing team performance over personal targets. The team spirit that you acquire while working in a professional environment is different from what you achieve in graduating days.

Thus, these were five important things that work experiences can teach you and thus help you in career growth and progression. People who can make optimum use of their work experiences gained, will surely have a promising and long career span in the near future.
