Thermal Stresses is a type of force experienced by any object, whether static or moving, due to environmental and physical factors. We can find different stress types like longitudinal stress, radial stress, thermal stress, and more. The common factor in all the different stress types is that the object's area remains the same, and the force also remains the same. The only thing that differentiates the various types of stress is the nature of force applied to the object. In thermal stresses, the temperature acts as the applied force on the body, and hence it is termed as thermal stress.

Thermal stresses form an essential part of many exams, including the GATE, CAT, IES, ONGC, and more. Hence a quick look at the thermal stresses GATE syllabus will be helpful.

Important Thermal stresses Topics for GATE ME

We study thermal stress and its different implications. The applications and implications make the main thermal stresses topics for GATE ME and cover the major thermal stresses GATE questions.



Thermal Cracking

A significant factor involved in the materials testing domain is where we study cracks and shallows due to the thermal stress and its derivatives.


Annealing is an extensively used metallurgical process that helps you to toughen the given element.

Thermal Shock

It builds cracks and fractures in any given metal and is a result of the large temperature gradient.

Tips to Solve Thermal stresses questions for GATE ME

  • Thermal stresses are usually asked in the stress-strain portion of the exam. And hence you need to prepare the stress-strain part for this.
  • You should use different learning sources to prepare for the thermal stresses GATE questions and answers PDF for revisions.
  • Practice the thermal stresses online quiz that helps you analyse your preparation strategies.
  • Remember that thermal stress is always a significant reason for the metal cracks and can be found by the Vickers hardness test.

Importance of Thermal stresses in GATE Exam

  • Thermal stresses for computer science test your engineering ability to find out the stress that any given material/ element can handle.
  • You simultaneously need to know stress-strain concepts to answer these thermal stresses MCQ questions. Hence GATE also tests your ability to connect topics with real life-applications.
  • The exam tests your hold on the thermal stresses notes for ME, taught in the core engineering classes, especially the metallurgical engineering class.
  • It has real-life applications; it explains everyday phenomena like the cracks and fractures on the materials.

Q. How do we determine the thermal stress?

Thermal stresses are similar to the normal stress that can be applied to any object. The temperature plays the applied force's role. You can easily calculate the thermal stress using the simple formula of (Force/ Area).

Q. Which tests can be used to identify the thermal stress implications on any metal object?

Any metal objects may undergo cracks and fractures that can be known by using the Vickers hardness test. You can also use the Brinell hardness test.

Q. Name the device that can maintain a constant temperature and is used in constructing thermal devices?

Thermostats are devices that can control the temperature flow and maintain a temperature gradient while flowing. It is used in many electronic devices.

Q. Can thermal stress be varied with any object's density?

Yes, thermal stress is a density-dependent quantity and hence varies with the object's material.

Q. What are some applications of thermal stress?

Thermal stresses are responsible for many cracks and dentures that come on the metal. They are also used in the bimetallic strips of iron boxes.
