What are the 7 C’s of resilience?
To others, resilience is at the very heart of wellbeing and is made up of the 7Cs: competence, confidence, connection, character, contribution, coping and control.
I first came across the 7Cs through a Dr Pooky Knightsmith training course, ‘Building Resilience in Children and Young People’..
What is a modulus test?
Modulus of Elasticity or ‘Young’s Modulus’ is a measurement of the rate of change of strain as a function of stress. … It represents the slope of the linear portion of a stress-strain curve. A tensile test, also known as tension test, is probably the most fundamental type of mechanical test you can perform on material.
What is the modulus of toughness?
Modulus of toughness is the ability of a material to absorb energy in plastic deformation. It is defined as the amount of strain energy density (strain on a unit volume of material) that a given material can absorb before it fractures.

What is modulus of resilience used for?
The modulus of resilience is the maximum elastic energy absorbed by a material when a load is applied. The ability of a spring or a golf ball to perform satisfactorily depends on a high modulus of resilience.
What does the modulus of elasticity tell us?
Modulus of Elasticity, also known as Elastic Modulus or simply Modulus, is the measurement of a material’s elasticity. Elastic modulus quantifies a material’s resistance to non-permanent, or elastic, deformation. … Modulus is defined as being the slope of the straight-line portion of a stress (σ) strain (ε) curve.
How do you find the modulus of resilience?
The unit of the modulus-of-resilience is nothing but the quantity of energy absorbed by per unit volume of a body and the unit will clearly be Joule per cubic meter (J.m-3) in the SI system. The area underneath the stress-strain (σ–ε) curve up to yield = μ = σ × ε.
How ductility is measured?
Ductility is defined as the ability of a material to deform plastically before fracturing. … Two measures of ductility are elongation and reduction of area. The conventional means by which these measures are obtained is by pulling a specimen in tension until fracture.
What is the relation between elasticity and modulus of resilience?
A material’s resilient modulus is actually an estimate of its modulus of elasticity (E). While the modulus of elasticity is stress divided by strain for a slowly applied load, resilient modulus is stress divided by strain for rapidly applied loads – like those experienced by pavements.
What is modulus of resilience toughness?
By definition, modulus of resilience is the energy, per unit volume, required to deform a particular solid material up to its elastic limit under tensile testing. Modulus of toughness is the indication of toughness property of solid material. … Modulus of toughness is the total area below engineering stress-strain curve.
What is ductility example?
Ductility is the physical property of a material associated with the ability to be hammered thin or stretched into wire without breaking. … Examples: Most metals are good examples of ductile materials, including gold, silver, copper, erbium, terbium, and samarium.
What are the 5 skills of resilience?
Resilience is made up of five pillars: self awareness, mindfulness, self care, positive relationships & purpose. By strengthening these pillars, we in turn, become more resilient.
What are the 3 categories of resilience?
There are four types of resilience: physical resilience, mental resilience, emotional resilience and social resilience. These types arise when we face major life problems, situational problems and daily problems.
How do you calculate toughness?
In the SI system, the unit of tensile toughness can be easily calculated by using area underneath the stress–strain (σ–ε) curve, which gives tensile toughness value, as given below: UT = Area underneath the stress–strain (σ–ε) curve = σ × ε UT [=] Pa × ΔL/L = (N·m−2)·(unitless)
What is resilience mean?
Psychologists define resilience as the process of adapting well in the face of adversity, trauma, tragedy, threats, or significant sources of stress—such as family and relationship problems, serious health problems, or workplace and financial stressors. … That’s the role of resilience.
What is ductility formula?
Ductility is the percent elongation reported in a tensile test is defined as the maximum elongation of the gage length divided by the original gage length.
What is yield strength formula?
The most common engineering approximation for yield stress is the 0.2 percent offset rule. To apply this rule, assume that yield strain is 0.2 percent, and multiply by Young’s Modulus for your material: σ = 0.002 × E \sigma = 0.002\times E σ=0.
What is the difference between resilience and strain energy?
Strain energy is elastic — that is, the material tends to recover when the load is removed. … Resilience is typically expressed as the modulus of resilience, which is the amount of strain energy the material can store per unit of volume without causing permanent deformation.
