Strength of materials is a field in mechanical engineering, which practices in the behavior of bodies under the influence of an external load. The internal resistance of the body and the body’s deformation depend on the external load which is put on the body.
Knowing the material properties and analyzing the forces acting on the body is the basis for mechanical engineering and designing machinery parts.

Knowing the material properties enables not to exceed the allowable stress of the material and not to get deformation in a way the body cannot function. Usually there are strict constraints such as low cost or minimum weight. Material strength analysis gives the material’s resistance for stretching, pressing, cutting,
twisting and bending. Stress analysis analyzes the adjustment of a structure and the materials of which it is composed, to the strength and stiffness required from it.
Understanding the strength of materials allows the engineer to evaluate and determine the static and dynamic forces which one can operate safely on the structure.

Structure analysis helps the engineer to design under safety factors of margin in order to adapt the structure to the relevant ambient requirement. CaDCaM performs structure analysis using finite elements method by using advanced, high-end FEM software – MIDAS NFX.

Structure analyses in finite elements are divided into two main areas:

Static analyses – IMPLICIT

are characterized by relatively small shifts

Dynamic analyses-EXPLICIT

characterized by large movements and deformations – collisions, explosions etc.

Static Analyses

The purpose of static analyses is to calculate the stress formed on the structure, in assembly or on machinery parts, in static mode.

Static analyzes combine internal and external forces in the structure as detailed below:

    • Stress forces
    • Gravity forces
    • Concentrated forces
    • Screws closing forces
    • Acceleration forces

Static analysis calculates the stress on the material and the movements generated on the structure after activating forces.
Analyses are performed using FEM method (Implicit)

CaDCaM performs linear and non-linear static analysis.

CaDCaM combines these analyzes with the following types of materials:

    • Isotropic materials
    • Anisotropic materials

Dynamic Analysis

Dynamic analyses are aimed to determine the dynamic stress and movements which are generated as a result of operating the system.

Dynamic force is usually a cyclic force in a certain frequency or a series of cyclical forces in a range of frequencies, i.e vibration.

Dynamic analysesDynamic analyses are performed using FEM method in both IMPLICIT and EXPLICIT. In the field of IMPLICIT dynamic analyses include:

    • Random
    •  Sinus
    •  Seismic

In the field of EXPLICIT dynamic analyses include:

    • Collision
    • Explosion
    • Drop test

Dynamic analyses are performed in a steady state mode and in Transient mode.
CaDCaM performs linear dynamic analysis and non-linear dynamic analysis.

CaDCaM combines these analyzes with the following types of materials:

    • sotropic materials
    • Orthotropic materials
    • Anisotropic materials

CaDCaM also incorporates in dynamic analyses shock absorbers in order to weaken the shock intensity and the vibration inserted into the structure.
In this context, CaDCaM chooses for the client the suitable shock absorbers.

Modal Analyses

CaDCaM performs modal analysis for all types of structures and assemblies.

Modal analysis’ added value is significant and important to the mechanical engineer. Modal Analyses determine the natural frequency of the structure and form of vibration.

these values enable thet engineer to identify whether the natural frequency of the structure is far enough or coincides with the frequency of excitation .Moreover the engineer can identify the shape and direction of vibration in either of the calculated directions and to decide whether to weaken or strengthen the structure on these directions .

CaDCaM provides its customer animations of any form of vibration frequency on a wide spectrum of frequencies, as a map describing the relationship between the fluctuations.

Modal Analyses are also a prerequisite for random analysis and seismic analysis
