Q2. Material model for solid material
Ans. 
Material model for solid material refers to the mathematical representation of how a solid material behaves under different conditions.
• Material models can be classified as linear or nonlinear depending on the behavior of the material.

• Common material models include Hooke's Law for linear elasticity and von Mises yield criterion for plasticity.

• Material models are used in finite element analysis to predict the response of

Q3. What is non-linear materials
Ans. 
Non-linear materials are materials whose properties do not change proportionally with applied forces or stresses.
• Non-linear materials exhibit behaviors such as hysteresis, creep, and stress relaxation.

• Examples include rubber, plastics, and certain metals.

• Their stress-strain curves are not straight lines and may show curves or other non-linear patterns.

Q3. What is polymorphism
Ans. 
Polymorphism is the ability of a single function or method to operate on different types of data.
• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).

• Example: Inheritance in object-oriented programming languages like Java allows for polymorphism.

Q4. What are abstract classes
Ans. 
Abstract classes are classes that cannot be instantiated and are meant to be subclassed.
• Abstract classes may contain abstract methods that must be implemented by subclasses.

• Abstract classes can have both abstract and concrete methods.

• An example of an abstract class in Java is 'Shape', with abstract methods like 'calculateArea' and concrete methods like 'draw'.

Q5. What is an interface
Ans. 
An interface is a point of interaction between components, devices, or systems.
• An interface defines the methods that a class must implement

• Interfaces allow for multiple inheritance in programming languages like Java

• Interfaces are used to enforce a contract between different parts of a system
